[Bug 808184] Re: gedit crashed with SIGSEGV in XVisualIDFromVisual()

 

I really don't think that depends on a overlay scrollbar bug, even if
it's triggered by overlay scrollbar. The Stacktrace clearly shows how
Gdk is crashing even if the argument of the function (the screen) is not
NULL and I think is correct (the screen shouldn't change). Can it be a
race?

** Also affects: gtk+3.0 (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: overlay-scrollbar (Ubuntu)
       Status: Confirmed => Incomplete
