Description Sergey Kolosov 2016-09-08 13:16:40 UTC 
Description of problem:
Mate-terminal crashes if I try to detach tab, but then cancel an operation. The terminal crashes only if new tab does not leaving current terminal window.

Version-Release number of selected component (if applicable):
mate-terminal-1.14.1-1.fc24.x86_64

How reproducible:
Run mate-terminal, create new tab, try to detach tab by moving tab, but don't bringing it out of the current terminal window.

Steps to Reproduce:
1. Run mate-terminal.
2. Create new tab.
3. Try to detach tab by moving it(by pressing and holding mouse button), but don't bringing it out of the current terminal window, and then release mouse button.
The bug is reproducible only if you don't moving tab out of current terminal window. If tab was moved out of terminal windows, the tab is detaching, and didn't crash.

Actual results:
Terminal is crashed.

Expected results:
After mouse button releasing tab must be in initial place.
