I am restoring my KMail details from Lenny with KDE 3.5.10 to Squeeze with TDE 3.5.13, patched with Slávek's patches. I have copied .kde/share/apps/kmail from my backup to .trinity/share/apps/kmail. It wasn't a success. The klauncher didn't do anything. (At least, it probably did, but I have no way of knowing what!!) I then launched it by various methods, which are self explanatory. Finally, I launched it from the menu, and got the backtrace (or lack of it) below. It's pretty obvious that I have copied something across during the restauration that has gummed up the works. But how do I find out what? Or should I simply delete all the files that are there and start again, but if so, how? I gummed up kdm-trinity as well, but have managed to sort that out via Google. This one I am failing with. Once I get this installation going I'll try to be trouble-free, or at least quiet, for some time! :-( root@Tux-II:/home/lisi# kmail Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed WeaverThreadLogger: thread (ID: 3) suspended.

This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.
