Can you reproduce the crash, or was it a one off?

Well, upon reading the e-mail notice I got with your message, I tried to switch to Summary and got a crash again (backtrace below).  Switching from mail to calendar seems to generate a crash about every time.  Switching to summary seems to have success sometimes and crashes others.  I'll do some more testing to see if I can determine how often it occurs.

Philip,

I did some tests real quick.  Switching from Mail to Summary caused a crash 5 out of 5 times.  Likewise, switching from Mail to any other module produced a crash.  I can go from any other module and switch back to the summary or anything else without a crash.  Seems to be very specific to switching from mail to anything else.

Looks like the same thing as bug 102470. I'll mark as duplicate for now, and if you find a reason to suspect that it's not the same thing, please reopen.

(BTW, bug 102470 has a suggested workaround, which might help you)
