Bug#506656: krdc crashes very frequently

["erlk ozlr" <erlk.ozlr@gmail.com>]

Package: krdc
Version: 4:3.5.10-2

Hi,
krdc crashes very often and writes :
krdc: ../../src/xcb_lock.c:77: _XGetXCBBuffer:  Assertion `((int)
((xcb_req) - (dpy->request)) >= 0)' failed.

Crashes seem random, and I have no idea how to reproduce them.
