It seems the IMAP client crash I accidentally discovered in Thunderbird/Icedove was already known.
My report is a duplicate of a bug which was previously reported in 2007. Oops.

It really is impressive that it's 2 years old and not fixed, though. Still a good find. Maybe that'll convince someone to take care of it.
