Description Jorn Baayen 2002-08-01 01:36:36 UTC

Sometimes (not always) unreffing a gnomevfssrc causes it to crash, trace:
(can be tested by playing a lot in for example rhythmbox)

Backtrace was generated from '/opt/gnome/bin/rhythmbox'

Comment 2 Ben FrantzDale 2002-08-05 15:19:21 UTC

olive (on irc) tells me that I marked these as duplicates in the wrong
direction. I was just going by bug number (that bigger numbers are
dups of smaller numbers).

Comment 4 Thomas Vander Stichele 2002-08-10 22:48:34 UTC

Could someone tell me if this is still the case ? There have been
fixes put into cvs to gnomevfssrc.  Please let me know soon ;)

Comment 5 Bastien Nocera 2002-08-10 23:16:18 UTC

This is fixed as far as I'm concerned. I've been able to play songs
with Rhythmbox for 24 hours in a row without a crash. I think that's
gone now.

We might need a Gstreamer release for people to stop using the broken
gnomevfssrc though.

Comment 6 Jorn Baayen 2002-08-10 23:47:37 UTC

I'm still getting it with the latest cvs gst-plugins, especially on
quit or at the end of an album/group.

Comment 7 Jorn Baayen 2002-08-13 15:10:59 UTC

okay, found a reliable way to repro

update to the very very latest rb cvs, play something, and while
playing, quit. Whoop, there you go.

Comment 8 Jorn Baayen 2002-08-21 22:06:25 UTC

Changing severity to critical since it's quite a nasty one (still
getting it on exit and (sometimes) at the end of a list)

Comment 10 Christian Fredrik Kalager Schaller 2002-09-09 09:12:54 UTC

Wim Taymans have been trying unsucessfully to find this bug. A good
testcase would help a lot.

Comment 11 Wim Taymans 2002-09-15 11:42:58 UTC

gnomevfssrc performs gnome_vfs_init and gnome_vfs_shutdown based on
simple refcounting. gnomevfssrc should not open and shutdown vfs if it
was already initialized when the plugin loads.
fix in CVS

Comment 12 Olivier Martin 2002-09-15 12:05:48 UTC

Works with the latest gstreamer cvs. Thank you wim :)
