Some messages (sadly I can't identify which ones) seem to cause a loop in
Folder.php that make apache eat CPU like crazy.

In the meantime it throws thousands of errors in seconds, always these two,
repeated:

[client 200.55.89.156] PHP Warning:  implode(): Bad arguments. in
/var/www/html/horde/imp/lib/Folder.php on line 205
[client 200.55.89.156] PHP Warning:  array_pop(): The argument should be an
array in /var/www/html/horde/imp/lib/Folder.php on line 220


Looks like $parentparts is not an array? Maybe some typechecking can avoid
the problem, even if the display will not be correct, at least it will not
make apache hang :-(

I am having this problem about twice a week on a server with 14000 accounts.
