When a BadAccess failure occurs during registering shortcuts QHotkey will go into an infinite loop, spamming the console each iteration.

WARN: Failed to unregister hotkey. Error: BadAccess (attempt to access private resource denied)

This time I tested it seems to have crashed. Segmentation fault @ qhotkey_x11.cpp:133 (The XSync line).

Tried again, the SIGSEGV is reproducable.
