Description jensus 2002-11-17 14:33:28 UTC

Package: GStreamer
Severity: major
Version: 0.4.2.1
Synopsis: Rythmbox crash in gst code
Bugzilla-Product: GStreamer
Bugzilla-Component: gstreamer (core)
BugBuddy-GnomeVersion: 2.0 (2.1.1)

Description:
Description of Problem:

Rythmbox crashes sometimes when clicking on the next button.
The arguments passed to gst_scheduler_interrupt is both null.

The crash happens quite random, so I don't think it's a bad file, 
but rather a timing issue that causes the bug.

Comment 2 Christian Fredrik Kalager Schaller 2003-01-15 16:48:46 UTC

I am assuming that you are using a distribution with a i686 optimized
glibc, probably Red Hat. 

After tons of testing/debuging I think this bug is solved. It turns
out that using Red Hat 8.1 + glibc from Rawhide things start working,
so it seems there is a bug in the i686  threading code shipping with
earlier distro's. Downgrading to i386 optimized glibc is a workaround.

If you should happen to use something else let me know. I leave this
bug open for a little while more so I can see you confir/denym my
assumptions.

Comment 3 Jens Askengren 2003-01-16 01:16:09 UTC

The code was running on debian 3.0, libc-2.2.5.

Comment 4 Christian Fredrik Kalager Schaller 2003-01-18 00:21:15 UTC

Talked with our thread-master David Schleef. The threading code has been 
bugfixed heavily since 0.4.2.1 and the bug is probably fixed. I am
closing this bug due to this, but if you should encounter it with a
newer release please let us know. 0.6.0 is planed out in about 9 days.
