Bug#856156: vim-gtk: launching gvim as root from terminal crashes X server

[James McCoy]

Control: reassign -1 xserver-xorg-core 2:1.19.1-4
Control: affects -1 vim-gtk

Reassigning to xserver-xorg-core.  Vim's gtk2 code hasn't changed
significantly in some time, so it's more likely an issue with the glamor
driver.
