[Pan-users] Pan crasher in Task window

[Douglas Bollinger]

Could someone else try to replicate this bug?  I would like a confirmation
before I post it in bugzilla.

I'm using pan-0.110.

Start Pan, goto a binary group and select several complete binary objects to
get some d/l tasks in the queue.  Select all the tasks in the queue and then
press the delete button.  Pan should crash.  It does this every time for me.

I think I got gdb working correctly.  This is with debugging activated for
glib, gtk+, gnome-vfs and of course Pan.  Here's the bt I get:

(gdb) run
