Bug Description

This occurred while I was attempting to drag a tab from one gedit window to another. The tab didn't move when dragged with the mouse, instead the entire application crashed.

I've attempted to reproduce this and couldn't, so am unsure exactly what conditions cause the bug.

Happend to me once after I dragged a file from nautilus to gedit and then tried to open the same file by double clicking.

This is how I can reproduce it (and also why it not happens most of the times):

It always happens when I start one gedit instance from nautilus and another gedit instance from a gnome-terminal window

It doesn't happen when both are started from the gnome-terminal
It doesn't happen when both are started from nautilus
it doesn't happen when one is started from the launcher and another from terminal
it doesn't happen when one is started from the launcher and another from nautilus

... happened when dragging text inside of gedit. Very annoying, makes programming with it nearly impossible for it crashes frequently. How can the priority only be low?

I got this when I had Gedit running maximized on my top-left workspace with multiple tabs open, then switched to my top-right workspace and used the quicklist entry for opening a new window. After the window opened blank, it went unresponsive and eventually crashed.
