crash/exception in PC: NSLock again?

[Riccardo Mottola]

Hi,

PC today crashed several times, while simply opening a project and a 
source file.
I was able to get the stacktrace below.
It apparently is unable to alert the exception itself, I rebuitl base 
with debug symbols and could't get the problem again

At a first glance, could it be the "lock already broken" issue biting us 
again? I see the exception starts from [NSDistributedLock unlock]

So just guessing.

Riccardo
