Description of problem:
I switched to calendar view and Evo crashcrashed.  Each time I reopened Evo, it would crash when I first moved the mouse over the window.  I can switch to Mail quickly enough to avoid the crash but switching back to Calendar recreates the crash.  The calendar is on GMail.

Version-Release number of selected component:
evolution-3.12.8-1.fc21
