[cmview-devel] Null-Pointer background overlay

[Jose Duarte]

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.
