Actually, this sounds like this bug: https://github.com/cyrusimap/cyrus-imapd/issues/2839 (fixed last week in 3.0.11)
There is a Debian report for it too: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=933163

I guess we're going to see a lot of this here, as people start upgrading older systems to the new Debian stable and getting Debian's 3.0.8 instead of whatever they had before.

Oh, I'd forgotten about that! I'm going to add a note about this to the reconstruct -G documentation as well as the upgrade notes.

It is a different issue though: the impact of #2208 (since the crash was fixed in 3.0.8, anyway) is being unable to replicate due to missing GUID's. You need reconstruct with -G before upgrading if you plan to build a new server and replicate your old store to it (which you will find out when you try to replicate). But it won't affect in-place upgrades until you try to replicate them somewhere later.

#2839 is rather more annoying because it affects in-place upgrades and copy-files-and-reconstruct upgrades!

Cheers,
