Description Harald Hoyer 2004-09-14 12:52:52 UTC

Happened yesterday also with:
$ rpm -q mozilla
mozilla-1.7.2-0.3.0

Comment 1 Daniel Veillard 2004-09-21 14:31:54 UTC

I'm suspicious of the call to gnome_vfs_monitor_do_cancel()
especially after 132922 and 130967 . Do you still have
the system ? If the gamin version was < 0.0.9 I bet it's a 
duplicate of those bugs. In any case it would be good if you could
tell me if this happened too with a recent version of the gamin
package.

  thanks,

Daniel

Comment 2 Harald Hoyer 2004-09-21 14:42:15 UTC

didn't occure lately... 
$ rpm -q gamin
gamin-0.0.9-1

if it does happen again, I'll reopen.

Comment 3 Harald Hoyer 2004-09-22 13:47:59 UTC

happened again... now with thunderbird:

Comment 4 Daniel Veillard 2004-09-22 13:56:49 UTC

Hum, that doesn't look related to monitoring there.
I don't think it's gamin related in that case,

Daniel

Comment 5 Harald Hoyer 2004-09-22 14:24:29 UTC

well the function name gnome_vfs_mime_get_all_desktop_entries() says
it all.. maybe I have to live with that...

Comment 6 Christopher Aillon 2005-05-04 20:41:59 UTC

Is this still an issue?  There have been a bunch of fixes to this code since
thunderbird 0.8, and I just added another patch to the helper apps code to make
things take a slightly different code path to use newer gnome-vfs-2.10 apis.

Comment 7 Harald Hoyer 2005-05-09 11:52:01 UTC

much better in rawhide, was still an issue in FC3

Comment 8 Christopher Aillon 2005-05-09 14:39:30 UTC

Cool.  Marking as RAWHIDE, then.
