When I start gvim, I just get an window with the menu and tool bar, but the
main edit area is empty.
On stderr gvim outputs the following messages:

(gvim:17545): Gtk-CRITICAL **: gtk_widget_set_size_request: assertion 'width >=
-1' failed
*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

The problem appeared after installing Tumbleweed snapshot 20161104.

Most likely it is related to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842070
and caused by the upgrade of gtk3 (3.22.1 -> 3.22.2)
