In our company the home folders were switched from NFS to CIFS. All KDE users suddenly had severe issues with Kontact. It crashes on startup with the following backtrace:

-----------------

After several tries Kontact somehow manages to start up but presents a long list of new mail folders, all named like e.g. cifs4fe4, cifs5c46, cifs5d5f.
This is somewhat catastrophic as the decision to drop NFS in favor of CIFS is probably irrevocable.
