[imp] double entries in folders

[Jörg Hillen]

Hello

I found this behavior on the latast stable version and on the CVS-tree
When i move or copy a message to another folder I always get them twice in
the destination folder.
It doesn´t matter:
- what username i am logged in
- if the folder is source or destination
- if I move or copy
- what version of horde and imp I use

Some Infos:
dbmail is used for imap authentication
mysql
redhat 8

I hope s.o. can help me with this really annoying feature

thanks
jörg
