All it showed was how the SIGABRT was brought to the screen. Not what triggered the SIGABRT

Considering it was sometime in the AM, I did not have the ability to recall your tips. Unfortunately, I have not had the spare time to even try your suggestion out, but it's on the list of things that have to be done. Too many nights in the office 'til midnight, 4 and now 5 AM.
It's on the list.
But I have to mention that it's these magical unexpected moments when Objective C or Xcode says "I don't know what to do, so I'll just crash and leave you no useful info, unless you know that special secret" that can be rather maddening. I lost count of how many times (aside from this) that Xcode "Unexpectedly Quit" or "would you like to continue or crash" Friday night/Saturday morning.
Hopefully this week when we update to 4.5, much of that pain will go away. Fingers and other digits crossed.
Thanks again Jens, it's on the list.
