   Further to my previous posting, I have found something I think useful.
   First, I am using kmail 1.9.5 on OpenSuse 10.2, KDE 3.5.5. Looking in the tmp directory, I found that the temporary files created by clamav (klammailxxxxxx is the format of the name) actually contains the "lost messages", it seems even with the full header. I use clamav 0.91.2 and Klamav 0.41.
  When the folder was in the maildir format, some of the half destroyed (i.e. "Uknown") messages contained text referring to I/O errors or command that were not understood. If kmail filters the messages through clamav even when you are just trying to see a message that has already been received or copy/move it to another folder, this could explain the problem at least in some cases: kmail passes the message throug clamav, clamav creates the temporary file which contains the full message, but for whatever reason when clamav tries to "pipe" the message back to kmail, something doesn't work, so kmail ends up with partial garbage.
   This could also explain why the developer did not get to reproduce the problem, if he does not use clamav with kmail - the problem is not with the message "per sé" (some of the messages with the problem in my case are five lines of pure gibberish casual text I type on the keyboard, nothing big or complicated).
   I will try later to disable temporarily the filtering of the messages through clamav, and see if this makes the problem go away for new messages.
  It may be worth checking and trying this even with kde 4, before it is released - the problem was not being corrected because it was "unconfirmed", but it could happen again.
  Unfortunately I would need to think how (if it's possible) to pipe the contents of temporary clamav files to kmail tricking it into adding the messages correctly to the folders. Also, since the clammail files are temporary files, it is not said that this trick can be used to recover the messages in all cases.
