How did you manage to get this to occur? I've not had an issue like this yet.

Note: It occurred even for my own project that implemented the ShowcaseView Library. Had to comment that line c.setBitmap(null) to get it to work.

I've place the offending code in a try/catch block; it doesn't affect the running of the program in any way, so I'll mark this as wontfix.
