hi Michel, some progress at last; appended.
I did notice that it happened as Thunderbird (nightly cvs build) popped up its "biff" window, which appeared, but did not get painted. I was not moving the mouse at the time of the crash, nor were there any other screen updates occurring. I have a vague impression that this matches previous instances, but can't be sure.
Awaiting further instructions. cheers, calum. Program received signal SIGSEGV, Segmentation fault.
