Comment 1 James "Doc" Livingston 2006-07-17 03:57:41 UTC

The crash is inside the 'mad' element, so moving to GStreamer. I'm fairly certain I've seen backtrace like that before, so it's probably a dupe, but I can't find any bugs with the same backtrace.

Comment 2 Jan Schmidt 2006-07-17 07:04:54 UTC

Everything from this bit down looks messed up to me:

+ Trace 69378

#49 rb_player_gst_new
#50 rb_player_close
#51 rb_player_gst_new
#52 rb_player_open

Comment 3 James "Doc" Livingston 2006-07-17 07:14:44 UTC

The thread with the signal handler call in it was thread 2, not that one:

Comment 6 Tim-Philipp Müller 2006-09-21 14:35:11 UTC

 - can anyone reproduce this reliably?

 - is there a specific song this happens with
   or does it happen randomly?

 - is anyone able to reproduce this with full
   debugging symbols? (ubuntu users should install
   the gstreamer0.10-plugins-ugly package)
