RE: [Evolution] Evolution crashes when attempting to saveattachment

[Jeffrey Stedfast <fejj ximian com>]

No need to gdb as root

just do this:

killev; gdb evolution-mail
(gdb) run

wait ~10 seconds or so...

in another terminal start evolution

now when evolution freezes, there is no need to race to start gdb, since
gdb is already attached to the evolution-mail process.

in gdb, just type:

(gdb) thread apply all bt
