Hi, Karolin!

Unfortunately I believe this makes an emergency interim release necessary. Sorry for that, but data corruption is really, really bad.

Volker
Yes, I'm afraid I concur with Volker. This can cause file corruption, and the *single* thing file servers must do is not corrupt files. So this is more important than a security release IMHO. Sorry :-(.
We need to backport full tevent releases, otherwise someone could still build against a broken system libtevent.

I'm preparing tevent 0.9.34 and push it to autobuild shortly.
