Description of problem:
1. Open two terminal tabs within the one window
2. Drag either of the tabs to an open part of the screen.

The expected result is that this detaches the tab from the window. Instead, gnome-terminal just crashes.


Version-Release number of selected component:
gnome-terminal-3.13.0-1.fc21
