[libdispatch-dev] BUG in libdispatch: 10F569 - 1730 - 0x11

Hi, My system (MacBook Pro) is crashing/freezing regularly 20 seconds after a wake up and the last message in the Console.app before the crash is a SystemUIServer[184] BUG in libdispatch: 10F569 - 1730 - 0x11 I downloaded the git repo to find out what this means and if it is really related to my system freeze. according to queue.c the format of this log is _dispatch_log("BUG in libdispatch: %s - %lu - 0x%lx", _dispatch_build, (unsigned long)line, val); So build 10F569, line 1730 (which file?), value 0x11. Anyone can tell me exactly what this error log means , how to workaround it or point me to the right forum to ask? Thanks /Rubén -- /Rubén
