[imp] Uninitialized string offset: 0 in ....../horde/imp/lib/Folder.php on line 170

[Sean]

One of our imp users was getting the following messages after logging in. I
had a look in the mailing lists archives and found replies to posts about
similar error messages which suggested reinstalling horde/imp.
What I actually found the problem to be was a file named .mailboxlist in the
users home directory.
Not completely sure what they did to create it but by deleting that file it
solved the problem.
Thought I'd pass on the info in case it helps anyone else. :o)
