berusky2: Abort in XCB code

[apoleon]

Hello,

this is Debian bug report http://bugs.debian.org/722637.

After playing the game for a while in Training mode, the game aborts when exiting the game by using the ESC key with

[…]
ap_Release_Play_List
ap_Release_Material_List
ap_Release
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
berusky2: ../../src/xcb_io.c:179: dequeue_pending_request: Assertion !xcb_xlib_unknown_req_in_deq' failed. Aborted ---

This bug might be related to the segfault in XSync on exit bug. After searching for those error messages, I have found out that it is sometimes necessary to call

XInitThreads() to make X aware that it's running in a multi-threaded application. I have also found similar backtraces that were submitted to the Fedora distribution.

The steps to reproduce this bug is:

1. Start Berusky2 and hit ESC to quit the program.

I can only reproduce it on i386 so far. After the first quit I get #18
On the second "Start+Quit" I see the error message reported in this bug report and sometimes on successive tries, I get this error and a long backtrace.

Error in `berusky2': double free or corruption (fasttop): 0x0000000002aabbe0 ***

This was reported separately in http://bugs.debian.org/722693.

Probably all bug reports are somehow related.
