Bug 1008078

Description of problem:
the hang occured while sending an email from my gmail-account (not included via online-accounts, but manually). klicking send left evolution in freezed state. closing the window did not raise the "does not seem to respond"-dialog but causes evolution to crash (as what this is the crashreport for). the email i tried to send was in "sent" folder but i have reasonable doubt that my email was not sent. 

* gnome-session was restarted before
