Evolution crashes starting today (Sept 28).
I track rawhide, it worked fine yesterday.
I have evolution-2.0.0-2.

It crashes when I change components, but does not crash
if I open particular components with component= on the cmdline.

Here's a trace - I don't know how helpful it will be:

Program received signal SIGSEGV, Segmentation fault.
