debugging unrecognized selector

I am seeing a crash in an iOS app and while I can reproduce it I am
still struggling to find the location in my code because the debugger
only stops in UIApplicationMain. What I am seeing in the log is

2014-05-16 09:46:56.796 MyApp[30998:60b] -[__NSCFString CGColor]:
unrecognized selector sent to instance 0x10debb640

Checking the address with `po` I can see the string. But it still did
not help to find where this happens. I added the following
breakpoints:

* All Exceptions
* -[__NSCFString CGColor]
* -[NSString CGColor]

but the CGColor breakpoints are not catching this. Why not?
How would you track this down?


I hope this is not too OT. If it is please let me know where to ask instead.

cheers,
Torsten
