Comment 120 for bug 704623

Just to clarify, I looked at the BMO bug again, and Miroslav was experieincing this problem with Global search/indexing disabled. So, something else is pounding the msf files, apparently.

I only found an article about firefox, but this works for thundebird too, to run under gdb:

$ thunderbird -g -d gdb
(gdb) handle SIG33 noprint nostop
(gdb) run

(with xulrunner and thunderbird debuginfo installed, obviously)

I'll try it on my desktop which exibits this and see if I can get a useful backtrace.
