Infinite imap decodeLine while loop

[weierophinney]

I just got a case where a line as follows: [LIST (\HasNoChildren) "/" {54} caused the while loop to run indefinitely.

I suspect ist this space character appended, which will cause the while (($pos = strpos($line, ' ')) !== false) { to run indefinitely? Not a nice thing to happen ^^ .

Im guessing {54} is a prefix to say that the next 54 Characters could contain special chars: (in my case Aufgaben/to dos/Landingpage "meine Immobilie im Alter". It probably meant the quotes.

It seams to work when I remove the space on L217.
