Thanks Dieter - at least I know what's causing the error.
Now I only need to find out why :-)

The error has been introduced after I switched to use PluggableUserFolder 
with my own SessionLogin plugin - maybe I should start to look for the 
cause there.
Why the reindexing tries to write to a session is a very good question - I 
actually have no idea.
Hmmm ... any good hints on how to debug this? (Would be nice to know *what* 
it's trying to write to the session)
