Comment 1 Marc-Andre Lureau 2008-06-02 17:43:36 UTC

update_from_option () seems to be problematic...

Comment 2 Marc-Andre Lureau 2008-09-01 17:44:29 UTC

I don't see any problem in the gnome-media code. Maybe two instance of the same v4lsrc causes crashes. 

Reassigning

Comment 3 Wim Taymans 2009-12-21 11:31:26 UTC

needs more info..

Comment 4 Pedro Villavicencio 2009-12-21 14:10:47 UTC

i'd be glad to ask to the reporter on ubuntu about that info, what else is needed? Thanks!.

Comment 5 Tobias Mueller 2010-03-30 18:14:35 UTC

Reopening as I can't see any open question.

Comment 6 Tim-Philipp Müller 2010-03-30 22:39:45 UTC

I have no idea what's going on here. The issue sounds vaguely familiar though, I wonder if we fixed something somewhere at some point.

Questions:

 - is/was this reproducable? (Or was it a one-off crash?)

 - does this still happen with newer versions of GNOME/GStreamer?

 - if yes, could you get us a valgrind log?
