Are you at MPI with a mysql connection? That would be my first guess: no
connection to the mysql server.
I guess the stack trace is longer that what you posted, is it? The
actual connection failure would come a lot further down, then that
usually leads to a null pointer elsewhere.
Anyway if you post more details so I can reproduce the test maybe I can
help more (what pdb, what exactly were you doing etc) I've just tried
choosing some background overlays in the contact map view and it worked
fine.
