I am using an aluminium MacBook late 2008 (Macbook 5,1) with OS X 10.8.2 installed. When I run UP 1.4, here is the console screen:
laptop:MacOS abc$ ./UP

2013-02-04 18:35:32.329 UP[3937:9823] NSAlert is being used from a background thread, which is not safe. This is probably going to crash sometimes. Break on void _NSAlertWarnUnsafeBackgroundThreadUsage() to debug. This will be logged only once. This may break in the future.

Sometimes, when I click the OK button of the print dialogue and after (?) it loads the data to the printer, one of the pthread crashes. From my memory, it say something about "floating point exception" This only occurs sometime, which leads me to think this may be some form of data race issues, especially after seeing the above message.
I can't include the backtrace, because the current run, I can't reproduce the crash. Since the crash occurs only sometimes and pthread is used, this makes me think that perhaps there may be data race.
Could you please have a look?
