Fix a silly "except '':" clause. This should have been "except:" -- I

must've used this to disable the exception handling temporarily to
debug the exception formatting machinery, and forgotten to re-enable
it before checking in.

Unfortunately, this made it into the ZODB 3.1 release, making this a
3.1.1 backport candidate.
