Operating System: Linux 3.19.5-100.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to open a message in kmail when the program stopped showing the preview, a popup showed the message was downloading but never completed, and when I selected "cancel" kmail crashed.
