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.
