Description TS 2010-12-09 01:38:02 UTC

I am having an multi-thread application which hangs after I upgrade to FC14. There is one thread consistently calling XNextEvent for X Window event; while another thread needs to communicate with X Server for some operation on the X Display which will wait for _XReply. Deadlock seems to be happens in the xlib/xcb library in this situation. 

The version of xlib and xcb are: 
libX11-1.3.4
libxcb-1.7.1

I try to upgrade to libX11-1.4.0 but this issue still occurs. However, the application has no problem after I downgrade to libX11-1.3.3.
