Complex Indic scripts cannot be displayed correctly

Bug Description

Binary package hint: firefox

The page

http://tinyurl.com/pk38t

displays correctly with Konqueror in Kubuntu 6.10 Edgy but not with Firefox 2.

In Dapper, invoking Firefox 1.5 with

MOZ_DISABLE_PANGO=0 firefox

fixed the problem, but not now.

Moreover, invoking Firefox 2.0 in Edgy with

MOZ_ENABLE_PANGO=1 firefox

does not fix it either.

Just to be sure, I have installed the Tamil language packs:

language-pack-ta-base
language-pack-ta

but it makes no difference.

Others have also recently experienced this problem. See:

So, the problem is likely localized to Firefox 2.

Chandra,

I see what you mean about the font being rendered in the wrong order. Would you mind installing the mozilla tarball from mozilla.com to see if the issue exists upstream?

Thanks
David

I downloaded firefox-2.0.0.1.tar.gz from mozilla.com and tried to execute
./firefox in the directory in which I had uncompressed the archive.
Unfortunately, I got a segmentation fault. When I tried to run ./firefox-bin, I
got this error:

./firefox-bin: error while loading shared libraries: libmozjs.so: cannot open
shared object file: No such file or directory

Interestingly, after the latest security fix for the Ubuntu firefox package, the
Indic fonts seem to be rendered correctly.

FYI, I think that the .deb that caused the problem rendering Indic scripts was:

firefox_2.0+0dfsg-0ubuntu3_i386.deb

and the package that fixed it was:

firefox_2.0.0.1+0dfsg-0ubuntu0.6.10_i386.deb

I will attach the about:buildconfig page and a PNG image of the correctly
rendered Indic script at launchpad.

May I request that whoever builds these packages does not change options between
succesive builds (especially for security updates) so that functionality is
invariant.

Thank you so much for your attention.
