I'm currently using Debian stable,which provides KDE 4.8.4 and KMail 
1.13.7.  I used to use testing, but went to stable when testing got 
KDE 4.12.4, which in turn provides a new KMail. But I can't seem to 
migrate my mail and settings from 4.8.4 to Trinity's Kmail.  I tried 
just copying directories, but got nowhere.    Any hints. pointers etc. 
appreciated.
