Bug#749131: briquolo: Somtimes crashes with a segfault

[Helge Kreutzmann]

Package: briquolo
Version: 0.5.7-4
Severity: normal

Most of the time briquolo runs just fine. However, sometimes it
crashes with a segfault.

I rebuild briquolo with DEB_BUILD_OPTIONS="noopt" set and ran it under gdb until it
crashed. Unfortunately, X was blocked from input (both mouse and
keyboard) while the crashed briquolo was present, so I killed it frum
the console (not the gdb process, however). 

In gdb I had the following output:
Program received signal SIGSEGV, Segmentation fault.

    at CasseBrique.cpp:254
        ch = <error reading variable ch (Cannot access memory at address 0x3e50170d160)>

As this is my first crash under gdb, I cannot say of course if the 
same positions hold for the other crashes, too.

If you need further information, do no hesitate to contact me.
