Description comicfans44 2014-07-15 11:37:07 UTC 
I found GstGLVideoMixer crash when dispose after commit 71c81a (aggregator: Avoid destroying sources we do not own)

pipeline created as 

videotestsrc ! glvideomixer ! glimagesink

close the gl window , gdb shows as following:

GLib (gthread-posix.c): Unexpected error from C library during 'pthread_mutex_lock': Invalid argument.  Aborting.

backtrace as following:

Comment 1 Matthew Waters (ystreet00) 2014-07-15 14:19:41 UTC 
I cannot seem to reproduce with latest master and latest glib from the stable branch (2.40).  What version of glib is being used here?

I'm on Ubuntu 12.04 32bit ,with glib 2.32.4, is this version too old ?

(In reply to comment #1) 

seems that it's related to glib version. glib-2.40 / 2.38 have no such problem.
Comment 4 Matthew Waters (ystreet00) 2014-08-01 01:04:21 UTC 
Resolving as fixed in glib stable.
