Version: 1.12.1 (using 4.3.1 (KDE 4.3.1), Debian packages) Compiler: cc OS: Linux (i686) release 2.6.31-rc7allah This bug is related to bug #173640. Kmail was used to crash when it was trying to move the sent email to the sent folder of an IMAP account, without having established any connection to that IMAP account. Now, instead of crashing, it moves the sent email to the _local_ sent folder. Which means i will manually have to move it into the right folder. Can't you just establish the IMAP connection when it is needed?
This is something you can configure in your transport settings. I'm so free to mark this as a duplicate of a wish to do that automatically. *** This bug has been marked as a duplicate of bug 198620 ***
