I have the same thing happening as n8oay
-when booting up from a new checked DVD I got the same error message.
When trying to report it to KDE as the message asked,
it showed another error message.
I clicked it off and all went smoothly from there.
On a second try I clicked off the first error message and all went ok.
There is no actual crash,
just the display of the error message which needs to be closed.
I assume that as Old-Polack says- the message is an error.
Not an ideal situation but easy to live with.
