Re: Interesting error in GWorkspace

Hi Eric

Here you go...

the filename it tries to open at line #3 is:
/Local/Applications/GWorkspace.app/Resources/FileManager.tiff

The image is valid, PRICE can open it without problems.

I get this error many times, sometimes with different stacktraces, like:

the other error I can't break into. I put a breakpoint in 
NSAffineTransform.m line 253 but I never break into it, it is strange.
