Exception while running Inspect->Code

In 3281, I'm hitting an exception while running Analyze->Inspect Code on my whole project or module.

I think it might be an IDEA core problem rather than
a problem with any particular inspection, because
I tried lots of different combinations of Inspect Code
with just one inspection or a bunch. Hits this
inspection every time.

No message
java.lang.NullPointerException
