I reported this in Bug 104956 already but it was closed due to its complexititvity:

I now AGAIN lost my hole Mail in my Inbox using kmail 1.9.5 from KDE 3.5.5 (Kubuntu)! 

What I did: 

1. I deleted several mails - mail by mail - in my Inbox. While deleting a mail KMail suddenly crashed (what it does from time to time when deleting mails also with normal imap). I then got this:

2. To be secure I then restarted KMail and selected "Lokalen IMAP Zwischenspeicher aktualisieren" (what means something like "Refresh local IMAP cache"). - Kmail then crashed a second time with this result:

After this step my cached Inbox was completely erased except one single mail (the first one in the folder). - I then checked my webmail access to this account. But there all mails were still in the folder. 

3. I then tried to start KMail a third time and also tried to again refresh the local IMAP cache. But it again crashed with this:

Now all mails also were erased from the server and so I lost my Inbox again. 

Later on I had another mail loss with my second account and dimap. I had 13 mails in my inbox and was reading several mails in this folder (GMX Account). I then right clicked my inbox and selected "Troubleshoot IMAP cache" -> "Rebuild Index". I got a message that rebuilding index was successful. Everything still looked fine. 

After the next synchronize 10 of my 13 mails were deleted from the server and by the second synchronize they also were deleted locally. I did this several times now by copying some mails in my inbox, rebuilding index and synchronizing twice. Each time many of the mails in my inbox were deleted after synchronizing twice.
