banshee 1.9.4-1ubuntu1 crashes on now playing view with wikipedia plugin enabled (by default, main banshee package)

Hint: I found a work around. Though I have only installed the banshee package, it comes with some default extensions.

I went in the Menu to > Edit > Preferences > Extensions and un-checked ALL of them. Quit the program. Restart.

Not it works perfectly. Changing to Now Playing. Even changing to complete fullscreen.

Console output from this successful run/workaround:
(At the end it says something about "NowPlaying." however it works with all extensions disabled..., but this maybe a good hint)

(PS: Please ignore the warnings about icons, indeed I messed up my icon themes on this test system)

Update:

I went to every extension enabled/disabled and it seems to be related with the Wikipedia extension, which is in the default set and enabled by default.

However, enabling/disabling extension only has an impact, when before quitting banhee completely and restarting. In the following two cases with the extension, hope that makes it clearer:

Case1: DOESN'T CRASH

In >Preferences > General:

Everything else default settings.

So all these make no problem for me. However, if I active the WIKIPEDIA Extension in running the program and playing music switching the view, it works.

But then restarting with the Wikipedia extension activated, Banshee crashes immediately when clicking on "Now Playing" again. Disabling Wikipedia and restarting again: Banshee works fine in "Now Playing" mode.

I guess this wikipedia extension is in the default set of banshee-package and enabled by default. That seem to be the problem for me. However, this can also be related to dependencies or libwebkit... ?

setting the bug status to 'confirmed'

I cannot reproduce it here with 1.9.4-1ubuntu1, please could you upgrade your banshee to the latest available in Natty and check if this issue persists for you?

Hi, I just upgraded to the new version and the behaviour is the same. I updated the bug description. Please see exact steps to reproduce below. Error message still:

The program 'Banshee' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 22997 error_code 8 request_code 70 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

With Wikipedia plugin enabled (which is by default) changing to "Now Playing" view. Mhm, these are ogg-files, which I play. Cover fetching works fine though for the browser view. Nothing related to that, I guess.

$ dpkg -l banshee

ii banshee 1.9.4-1ubuntu1 Media Management and Playback application

I tried now with ALL plugins disabled, and only Wikipedia plugin enabled. It crashes.
With all plugins enabled, but Wikipedia plugin not enabled it does not crash on the "now playing" view.

IMPORTANT to reproduce:
Please keep in mind, to activate the Wikipedia plugin in the Preferences dialog. Then fully exit Banshee (Strg+Q, not just in the tray, exit the program completely) then restart Banshee. Start a song or music track, change to "Now Playing view" then it crashes.

Christian, it doesn't crashed for me but while I was running banshee (1.9.4 in a fresh install of Natty daily build) with debug I get a similar output:

Could not configure libwnck support - System.DllNotFoundException: libgobject-2.0.so (in `Banshee.NowPlaying.X11')

however, such as said before it doesn't crash.

Well, since this is a weird behaviou I have sent this issue to upstream tracker so please keep an eye over https://bugzilla.gnome.org/show_bug.cgi?id=643616

wow, that was fast, according to upstream tracker this issue is a duplicate of bug https://bugzilla.gnome.org/show_bug.cgi?id=641515

Christian, you're actually seeing a different bug. Notice that in the description, the error message is an X11 message about BadMatch or something. Your error message is about a DllNotFoundException, which I have just committed a fix for in the Debian packaging. The DllNotFoundException issue can be worked around by installing libglib2.0-dev.

Please do not hijack bugs like this in the future, as it can cause quite a bit of confusion, and cause bugs to be erroneously closed. Similar symptoms do not always mean that the bug is the one and the same.
