Cursor changes to cross after dragging text in gitg

[Sergey Goncharenko]

How to reproduce:
1. Open any git repository in gitg.
2. Open Commit tab
3. Select some file in "Unstaged" section
4. Select some text in "Changes" field using the mouse (by the way, the selection background is the same as other text, so it's impossible to notice what's selected).
5. Drag this text by some pixels with mouse and drop it.

What I expect to happen: Nothing. Gitg just exits drag mode.
What happens: Default system cursor is changed to cross (with diagonal lines, see screenshot). It remains cross till reboot.

This is rather annoying because I see cross cursor in all applications. The only workaround I discovered is reboot.

I'm using Xubuntu 14.04. I've tried installing a clean Xubuntu in virtual machine, and the bug is reproducable.
