GUI crashes on program start (interrupted by signal 11 in module: unknown)

[amk@…]

When starting the GUI version of mplayer (gmplayer), it sometimes
(chances are 50:50) crashes during initialization of its GUI components
with this message:

MPlayer interrupted by signal 11 in module: unknown

Default configuration, command line is:
gmplayer -skin mplayer_red does_not_exist

That means, it doesn't depend on any specific video file. It crashes
before it even touches the video file. It doesn't crash always. Maybe
a timing issue during the GUI initialization. It doesn't depend on
CPU architecture (same bug on AMD Dual Core and Intel with HT).

The non-GUI version (mplayer) runs fine. So it looks like a problem
with the GUI itself, not with the video output in general.

I could not reproduce the crash when running within "gdb".

I will attach to verbose output logs, one when the GUI version runs
fine, and one when the GUI version crashes. Maybe it helps to see
where it fails.

System is Fedora Linux release 12 (x86, 32 bit). MPlayer did not
crash on old Fedora 10 a few months ago. Appended is the stuff
recommended in "bugreports_what.html".

Console output when GMPlayer does not crash

Console output when GMPlayer crashes with signal 11

[reimar]

The GUI is unmaintained, so there's not much hope it will be fixed.
Anyway, does it also happen if you use a different skin?
Also try updating, there may have been an alignment issue that is now fixed.

[amk@…]

Thanks for the effort, updated a couple of minutes ago, but it still crashes.
Also doesn't seem to depend on a specific skin (tried a couple of different ones).

Is it really true that the GUI is unmaintained? I'm confused. What exactly
does this mean? MPlayer should only be used by text console and keyboard?
MPlayer is such a popular video player. Come on, you can't be serious,
there must be some kind of nice GUI. And although it may be unmaintained,
I really like the GUI of GMPlayer very much. Excellent look and feel.
Never had any problems. Does exactly what I want and offers all I need.
Great thing! Unfortunately, Fedora 12 doesn't seem to like it. *sigh*

[reimar]

Try updating again.
If it does not work, move your configuration out of the way and/or try with -fstype none
The officially recommended GUI is SMPlayer.
The GUI being umaintained is supposed to mean "please try to find a different GUI that you like, because every time we look that the gmplayer code we feel a very strong urge to delete it and we probably won't be able to resist it one day".

[amk@…]

It looks like you got it! Haven't had a single crash until now.
Although it's not officially supported, I'd like to thank you
very, very much for finding and fixing this little bugger.

I've also tried SMPlayer as you recommended. Amazingly lots of
features. Unfortunately, it's not really designed to run the movie and
the control panel in different windows (it's possible, but then they
behave more like two different applications). And I really miss
the skins. ;-)

Well, I promise to give SMPlayer a try. However, thanks a lot
for fixing the old GUI (I still think it's really great) so that
users like me don't have to switch all at once and have got some
extra time to get used to SMPlayer.

[reimar]

Seems to be fixed

[amk@…]

MPlayer worked perfectly until the SVN snapshot from 2010-02-27 at least.
Haven't updated MPlayer since then.

Yesterday I downloaded MPlayer 1.0rc3 (dated 2010-05-30), and this old bug
is there again. Just like it had never been fixed.

I know the internal GUI is unmaintained... but maybe you could have a look
what happened here. Maybe there's something wrong with 1.0rc3 in general?

[amk@…]

Just downloaded the current SVN snapshot, and there the GUI works great.
The MPlayer 1.0rc3 archive seems to be kind of weird.

[reimar]

What's wrong is that rc3 is based on ancient code. This is not the only bugfix by far that's not included.
