Bug#863419: evince: selecting text and trying to drag it causes crash

Wed May 31 13:10:46 UTC 2017

Ok, I installed libgdk-3-0-dbg and managed to get here:

(gdb) break gdk_x_error
Function "gdk_x_error" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (gdk_x_error) pending.
(gdb) run far.pdf
Starting program: /usr/bin/evince far.pdf
