Some Windows CE debugging fun for you tonight...
First, sharpen your "ninja debugging skillz" by understanding VM layout on CE (read: recognizing the location of an address just by looking at it--wha*ta!). Then learn how to figure out which freaking function of which DLL threw that exception with Sue Loh's write-up on manual address to symbol resolution.
I'm not a big Windows CE fan, but I work with it every day, and I can't tell you the number of times I've needed to do this very process. Sue's article does a good job of breaking this down.
