After I've applied a patch from bug 543075, some things became strange (see there). Now I don't know if the program quit is relevant to this or not, but merging bugs might be easier than splitting... ;)

So now, I've compiled latest evolution revision 35830 in order to apply the patch to the newest version. I've then closed the folder tree of my exchange account and selected the junk mail folder. Evo crashed immediately. Now, everytime I start, it comes up with the message to disable mail preview which I follow, then evolution crashes (all other evo apps like alarm-notify, data-server and exchange-storage continue running) immediately after.

Hope this is solved fast, can't work now... :I
