I had typed up decent description here, intending to commit it *with* my
attachment. Sadly, the attachment wiped out my comments here. Ugh! So here goes
from memory:

Wireshark crashed on the first try for me in OSX (10.6.7, 64-bit). After that,
it crashed when I tried to reopen the File/Import dialog after cancelling.
Several crashes later, it took several cancels to crash at the press of the
button. In one instance, it froze instead of crashing.

I think the problem starts at
http://anonsvn.wireshark.org/viewvc/trunk/gtk/gui_utils.c?revision=37722&view=markup#l566
because I see a bunch of Gtk-CRITICAL messages after I step over this line:

(gdb) n
566        gtk_widget_destroy(win);
(gdb) n
