-- Information about the crash:
kontact was already running in a KDE session started on the local console.

Logged in remotely and started another session using nomachine's NX.  Within
the second session kontact started automatically at login.   It detects another
instance and offers to stop.  Selected the option to exit, then kontact
crashed.
