thunderbird crashed with SIGSEGV

[Leon Adato]

Thunderbird is crashing frequently and (seemingly) randomly. Typically it occurs when the system has been idle for a while (overnight, when I go on a break, etc). Sometimes shutting down all browsers (I usually run Firefox and Chrome) will let me start everything back up and be stable. Sometimes only a restart will get me back in business.
