KMail Disaster - "index file" problems
 

After a power faliure, the account that was logged on cannot open KMail anymore.
It flashes (approx.):

testfile index out of date

then

could not synch index file

And does not open.
The remote location that Mail is in is mounted and works fine.
Another account can open KMail fine.

What's wrong?
