the fact that the system was at high load (about 3 or higher according to the "Load Average (1 min)" display in ksysguard) may be relevant.

Confirming... One would guess has to do with bug 332160 landing yesterday. My 2006-11-29 branch build always crashes when I get new mail now. (Trunk works just fine.) Turn off the "show alert", and all is ok. 

I might add I didn't see this problem when I tested that fix on branch like a month ago.

Here are some of the crashes, looks to be all in different places: TB26661170W TB26661539H TB26661205E TB26660957X.

The crashes mentioned under bug 362215 also seem to be in various places.

I've backed out Bug 332160 on the branch where this was crashing.

No crash. But (like until day before yesterday) no alert display either.

This was fixed when Scott backed out the patch for bug 332160. ->FIXED

I propose to wait until the new fix for bug 332160 lands on the Tb-2.0 beta builds, and then mark this bug VERIFIED after ascertaining that that new fix does not reawaken the crash.

Fix for bug 332160 landed on 1.8.1.1 branch between 20061206 and 20061207 rounds of nightly builds while I was asleep. Just saw the new alert slider. No crash.

I'm marking this bug as VERIFIED.
