Review request for KDEPIM.


Summary
-------

When starting Kontact for the first time on a system where no KDE is running there is a race between Kded to create a KSycoca database and Kontact to access the KSycoca database.
In those cases Kontact starts without plugins and looks like the attached screenshot.
On most GNU/Linux systems this code will never be reached but on Windows this happened reliably at the first startup for each new User starting Kontact.

Testing on a 2,8 GHz dual core System showed that a two second sleep of Kontact is enough. So the 10 second wait timeout should suffice on most systems.
The added Messagebox in case the timeout is reached can be helpful to distributors or users with a broken setup.


This addresses bug 269807.
