           Summary: Import of old mails (Directory ~/Mail) into upgraded
                    Linux 10.2 installation seems to work. But selecting
                    some migrated folder hangs kmail
           Product: kmail
           Version: 1.9.5
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: reiner miericke net


Version:           1.9.5 (using KDE 3.5.5 "release 45.2" , openSUSE 10.2)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.18.2-34-bigsmp

After upgrading I used the file-->import, "Import from kmail" to migrate my old folder to the new version of kmail.
When the migrated folders appeare in the window (ok, folders sent and received didn't appear)I moved some from the migration folder into the "Loca folders". But when selecting another folder kmail hangs. CPU goes to 100% and kmail has to be killed. GUI hangs too. 
Using strace I got the following output:
