Comment 2 for bug 580586

I tried different revisions between 0.6.4 and 0.6.5 and the first one that freezes is rev. 1222:
http://bazaar.launchpad.net/~listen-devel/listen/devel/revision/1222

If I break into listen with gdb after freeze I can see that listen is stuck inside xcb_wait_for_reply
(which calls poll() in a loop):

So this can be actually a bug in libxcb.so.1.1.0.
