Bug#722639: berusky2: Segfault in XSync on exit

[Guillem Jover]

Package: berusky2
Version: 0.9.1-1
Severity: normal

Hi!

At some point I got this when exiting the game (with the Esc key):

,---
[…]
ap_Release_Play_List
ap_Release_Material_List
ap_Release
Segmentation fault (core dumped)
`---

The backtrace for that core dump is:

Core was generated by `berusky2'.
Program terminated with signal 11, Segmentation fault.

This could actually be related to the XCB abort, just filing it
separately to avoid creating a mess of bug reports with possible
several issues intermingled, and because the reports can always be
merged.
