rendering glitch

Seems like this is most probably a GTK+ bug, but I'll start it here first:

 * Open the Characters search box
 * Type Ctrl+Shift+U then e731
 * Type Enter

The rendering of the widget hierarchy breaks impressively. Screenshot attached. The transparency in the screenshot is actually displayed as black on my screen. This is with gnome-characters-3.22.0-1.fc25 and gtk3-3.22.5-1.fc25.

Thanks for the report.  It is caused by an uncaught exception during vfunc_draw.  The attached patch should fix this.
