Will do and see what I come up with. A problem though, is that an __objc_error is not always responsble for bringing
the program down. Two other reports (from _NSPostBackgroundLayout on), look like this:
0 com.apple.CoreFoundation 0x9028def0 __CFArrayRepositionDequeRegions + 56
1 com.apple.CoreFoundation 0x90285e6c _CFArrayReplaceValues + 1472
2 com.apple.Foundation 0x90afc4f4 -[NSCFArray removeLastObject] + 192
3 com.apple.AppKit 0x9254a3bc -[NSSortedArray removeLastObject] + 48
4 com.apple.Foundation 0x90b11240 -[NSMutableArray removeAllObjects] + 68
5 com.apple.AppKit 0x9253db98 -[NSLayoutManager(NSPrivate)
_fillLayoutHoleAtIndex:desiredNumberOfLines:] + 2720
6 com.apple.AppKit 0x9258fa50 +[NSLayoutManager(NSPrivate) _doSomeBackgroundLayout] + 556
7 com.apple.AppKit 0x9258f6a0 _NSPostBackgroundLayout + 364
...
0 com.apple.AppKit 0x92e782ac -[NSLayoutManager setTextContainer:forGlyphRange:] + 0x17c
1 com.apple.AppKit 0x92eea9cc -[NSLayoutManager(NSPrivate)
