Bug 1031576

Description of problem:
I saved mail into .mbox file. Then I changed window to Firefox (I didn't shut down Evolution). Then I clicked tab and opened home folder in Nautilius. Then I opened .mbox file. Then Evolution asked me to import file. Then it imported file into Evolution. Then, when I was in Evolution I saved attachements of mail message to folder. Then I closed Evolution. And this is the moment when Evolution crashed.
