           Summary: check-in after working offline kills inbox

Kmail deletes all mails from an inbox.
Steps to reproduce:
- work on a client machine with kmail configured for dimap
- switch to "offline" mode
- on the server use another client and delete a message from inbox
  (I use pine as a workaround for the most infamous unresolved wish
   http://bugs.kde.org/show_bug.cgi?id=17513 ).
  when terminating the client actually perform the deletion.
- on the client machine click on "Check Mail In"
  This pops up a question, asking me if I want to go online.
  answer by clicking "Online"
=> The inbox on that client machine is wiped completely. ALL MESSAGES DISCARDED.

The first time this happened to me, I couldn't believe what I saw, and
clicked "Check Mail In" for a second time: The worst mistake I made in years:
Consequence: the delete events were propagated to the server resulting in
irrecoverable loss of all messages in the inbox on the server, too.
