[imp] Dot files & Undefined index warnings

[Chuck Hagenbuch]

Quoting Scott Elcomb <selcomb at scm.tbgna.com>:

> I'm having an issue with showing unsubscribed folders, wherein "Undefined

> show them.  There are other warnings & lines, but I expect they're

This problem has been seen and fixed numerous times, but since you don't say
what versions you're running, I can't really tell you anything other than
try the latest IMP (3.2.1).
