I only ever reproduced this with electric-fence running, and it would
happen as you type chars into the filter entry. I'm not sure why it
needs electric-fence.

Its almost certainly a GTK bug:

http://bugzilla.gnome.org/show_bug.cgi?id=346800

It won't show for those on older GTK versions, the text in the bug above
suggests it is present in 2.8, but it isn't (often?) triggered.

PeterB:

your crash - did it definitely segfault, or could it have been a GTK
abort?

Anyway... still the other bug to chase, that one probably is ours.
