linthesia crashes with GdkGLExt-WARNING **: cannot load PangoFont

Thanks for your contribution. Could you please also forward that patch to Debian (and/or upstream).

This bug was fixed in the package linthesia - 0.4-1ubuntu1

linthesia (0.4-1ubuntu1) natty; urgency=low

  * src/TextWriter.cpp - change font to Serif, fixes pangofont error (LP: #663962)
 -- Roy Jamison <email address hidden> Wed, 20 Oct 2010 17:21:04 +0100

I do get the same error with linthesia 0.4.2-1 on Natty with all updates installed, so this problem still seems to exist.

Robert Roth, I have the same issue , I'm running natty amd64

I have set this back to Confirmed, as I'm still having this issue with an up-to-date natty, maverick, and also by building from the source.

Also raised the importance, as the application does not start, so it does affect all users trying to use it.

A workaround is edit with gconf-editor the field apps/Linthesia/font_desc, with a font that is sure exist on your system (like Arial)

Hi , I've the same problem. I don't know what I can do!

I have the same problem, installed Linthesia from Ubuntu Software Center. Is there any workaround or any updated version with a fix? I really want to use Linthesia instead of synthesia + wine. Thanks!

The workaround of lombardi davide (lomdav) works, but the font looks ugly...
I hope this bug will be fixed soon

Went in and fixed the font like lomdav said (tried Ubuntu, FreeSerif, and Arial), but still no dice. I've got Timidity as my midi synth, not sure what else to putter with.

All those above are with different font, .. when is this crap going to be fixed properly !?

So, I managed to get it working. The Arial font doesn't work for me (on Debian testing) but "Nimbus Sans L" did the trick. This font is included in ghostscript package called libgs9-common. It includes Nimbus, URW, Century Schoolbook L, Dingbats and Standard Symbols L. Note that most of these fonts have L on their names, maybe it means something, I dunno. These files are located at /usr/share/ghostscript/9.05/Resource/Font/. I tried some other regular OpenType and TrueType fonts but Linthesia crashes with every of them. Maybe my glibmm/pango/whatever else doesn't have support for these and it was introduced in more recent version. I have no idea. Though "Nimbus Sans L" and "URW Gothic L" work fine here, give it a try if Arial doesn't solve the problem.

precise amd64
ii linthesia 0.4.2-3

Here the 'Nimbus Sans L' produce the same crash. Hey that's LTS and we should get a backport without this problem.

This issue should be fixed at 0.4.2-5.

I upgraded only linthesia from raring at precise arm ("glib-networking glib-networking-common glib-networking-services libglib2.0-0 libglib2.0-bin libglibmm-2.4-1c2a" were upgraded alongside).

But linthesia still crashes with the same message !!!

Hi! Use Ubuntu 13.04 Linthesia start with error .... Changed the config, prescribed font Nimbus Sans L instead of Serif, but Serif font again.

It is still present the last time i was able to get it to work was like 3 years ago !?

Hi everybody.
I have written a fix.
It is different from the debian one: instead of forcing a hopefully installed font, mine queries the X server for the available fonts. This way, the fix should work on every platform, regardless of whether Arial, Serif or Sans is present.

Victor's patch seems to fix the crash for me,
would be nice to see it integrated in next packagage revision, as right now the package from the repository is simply unusable

In gconf-editor, in "apps/Linthesia/font_desc", I put successively Nimbus Sans L, URW Gothic L, Arial, Times New Roman, courier, sans and serif and nothing worked. But when i put 'clean' (without quotes), linthesia started successfully

I'm amazed that this bug bug is carried through the releases from 12.10 up to 13.10 without fix. Now i have rollbacked linthesia to the 12.04 LTS package called

linthesia_0.4.2-2ubuntu1_amd64.deb

an yes it start very well. It does not matter which font is set in gconf-editor, this oldie package runs also mit "clean".

If it's complete impossible to fix a package over years, why is rollback not the proper method?

when o when is it going to be fixed, ..

same issue here on linux mint 17.1. If this package is no longer going to be maintained please freak'n remove it from the repo's otherwise fix this damn issue.

As Victor said, it seems that a way to workaround the bug is to execute gconf-editor and to find a value for apps/Linthesia/font_desc that prevents the crash. At least "courier" worked for me on Debian (suggested in the comment of the patch).
