[Pan-users] A little gdb debugging help?

[walt]

I got in the habit of running pan in gdb a few months ago, when crashes
were not rare.  (I haven't seen a crash since I began the habit, thanks
to Charles  :o)

However, I just noticed that when I try to change the 'Save to' directory
in the 'Save attachments' dialog, gdb halts pan with this message:

Program received signal SIG33, Real-time event 33.
[Switching to Thread -1253004384 (LWP 9959)]
0xb7fd9410 in __kernel_vsyscall ()
(gdb)

When I tell gdb to 'continue' I just get the same message every time.
Is this the expected behavior when running pan in gdb?
