The difference between maildir and mbox is that in the case of mbox the=20
compacted mbox is stored in a new mbox file. This new mbox file=20
replaces the old mbox file and in order for this replacing to work the=20
old mbox storage must be closed and the new one must be opened. Without=20
having a closer look at the code I currently don't know how to open the=20
folder again.

A much safer solution for this bug is the conversion of all mbox folder=20
to maildir format.
