Comment 1 Tim-Philipp Müller 2006-08-28 22:52:10 UTC

Can you reproduce this?

If yes, could you run totem (or 'gst-launch-0.10 playbin uri=sftp://foo@bar') in gdb with G_DEBUG=fatal_warnings, wait until it aborts and then do

 (gdb) frame #10    (or whatever frame search_by_entry() is at according to 'bt')
 (gdb) print *feature
 (gdb) print *factory

and paste all the output you get from that?

Comment 2 Christian Neumair 2006-08-29 17:16:56 UTC

Thanks for your feedback!

After installing the gstreamer debugging packages, I suddently got another bt:

After recompiling gnome-keyring myself (because there is no libgnome-keyring-dbg avail. for Ubuntu), the issue is gone.

Changing status to NEEDINFO, maybe we'll get a dup some day.

Comment 3 Tim-Philipp Müller 2006-09-25 11:17:54 UTC

Surely this is a bug in gnomevfs in the end? Still, it shouldn't crash/abort like this. Fixed in GStreamer core CVS HEAD:

 2006-09-25  Tim-Philipp Müller  <tim at centricular dot net>

        * gst/gsturi.c: (search_by_entry):
          Don't assert/crash here if a uri handler doesn't return any
          supported protocols. The list of protocols could be generated
          dynamically at runtime or at plugin registration, and an error
          in the underlying library shouldn't be fatal (#353301).
