Looks good to me; no more segfaults at shutdown. I'll point the Gentoo
folks at this, should give the issue quite a broad testing, based on the
high number of subscribers on the cc lists of the involved bug reports.

Will you release a 2.8.1 to address the issue? Given that it's a
regression, and could cause major data loss, I wouldn't want to wait too
long for this to get released officially, especially as the patch
obviously won't make things any worse.

Greetings, and thanks for the fix,
