Due to defective patch to replace deprecated "gdk_window_get_pointer"
in `gitg` the latter started to crash and lost most of its
drag'n'drop
functionality. Also it becomes very noisy on console during mouse
movements:
(gitg:26390): Gdk-CRITICAL **: gdk_window_get_device_position:
assertion `GDK_IS_DEVICE (device)' failed
Fortunately user provided corrected patch that fixed all the run time
problems as far as I can see. With your permission I'd very much like
to fix this mess in Wheezy. Please find attached .diff file with all
the changes.
