Screenshot of the Conflict Resolution dialog

Version:           2.0.95 (using KDE 4.6.2) 
OS:                Linux

I opened up my IMAP Inbox, saw a spam mail, selected it and hit Delete (befoew the content was loaded).  I was greeted by a Conflict Resolution dialog box which asked me to resolve a conflict in the metadata (how is a "regular" user supposed to answer this question?), see attached screenshot.  Jusdging from the modification time of the left column, it tried to resolve a conflict between a dummy/empty object and the then-loaded mail.

I just pressed Escape (which resolution is that?) and afterwards I couldn't find the mail in the Trash folder (the wrong one BTW, cf. bug 259422).

The debug output wasn't helpful either.  I posted it below; it appeared AFTER I dismissed the Conflict Resolution dialog.

Finally, I had a look at the local trash folder (is it supposed to be a broken Maildir?) and discovered that it contained 5 messages while KMail only displays 2 (I can't tell if the deleted mail is there since it was a spam mail I receive quite often; but the timestamp 2011-05-10 10:41 looks like its that mail):
