I tried setting a breakpoint on [NSException raise]. Didn't try on the [NSURL initWithString:baseURL:] but I'll try it tomorrow. Maybe that will help.

I tried to reproduce it but so far, I'm not sure what I'm doing different that will trigger the bug. The drag is from my app to the Finder. If I drag from within my app, the error never occurs. It really seems to be with the NSFilesPromisePboardType pasteboard type that this happens.
