Using DIMAP, when looking at the contents of a certain folder, mails are listed. Some mails are actually in other folders on the IMAP server
Mails are randomly distributed in IMAP folders.

Reproducible: Sometimes

Steps to Reproduce:
(Does not happen in all folders)
- Open a folder. (In my example, a folder where I keep the mailinglist kolab-users)

Actual Results:  
The folder lists mails (e.g. from kolab-users), but also lists mails that are in another folder. (e.g. Launchpad bugs)
When looking in the folder containing Launchpad bugs, these mails are missing.
It looks like the mails are moved.

Expected Results:  
The content listing of a folder should be correct. Only mails that are in that folder should be shown.

Note that looking at the IMAP server with another mail client does list the correct contents. When rebooting, mails can sometimes return to their correct folders, but other mails get thrown in the wrong folders.

I'm only talking about displaying the contents. It is possible to open those mails.

During mail fetching, you can see mails arrive. When wathcing mail arrive in certain folders, often the wrong mails can be seen temporarily.

I'm setting this to major. There is no data loss, but there is perceived data loss. Data can't be found in its expected place.
