Well, I moved the old one back for now. Anyway, I'm curious to know what data I'd supposedly lose by doing that.
I answered a similar question here recently: https://lists.opensuse.org/opensuse-factory/2017-08/msg00623.html There may be other things stored in the database though, in general I would expect this to be the case for all "special" things that are not supported by the "conventional" storage backends (maildir, IMAP, ...), e.g. certain mail flags that are not supported by your IMAP server, custom tags, things like that. If that could be a problem for you depends on your usage I suppose.
I don't think this describes the same situation. In that bugreport, mysqld and akonadi eat CPU and do disk I/O. In my case it's kmail alone (and no I/O I can see).
Well, you did mention high CPU usage and disk I/O by Akonadi and mysql too in your original mail... But ok, I read it completely again, and those problems apparently seem to be fixed by removing the database. If its actually kmail that uses up the CPU now, I highly doubt that switching the Akonadi database backend would have any effect though. Kmail only talks to Akonadi, not the database backend. As a side-note: The mysql errors mentioned do sound to me like the database got corrupted somehow... (the mysql internal part, not Akonadi's tables)
Is there a way to figure out what kmail tries to do?
Getting a backtrace with gdb, as Luca wrote. According to your problem description, it might be somehow related to message threading/grouping though, so try to turn that off maybe and see if it helps. I.e. try to switch to one of the "flat" options in View->Message List->Aggregation. Another thing that would probably be worth a try is to rename ~/.local/share/kmail2/ and/or the settings file (~/.config/kmail2rc). I think I heard about problems with corrupted autosaved mails in the past, and I think saved searches can (or could in the past) also cause such problems, but I'm not sure at the moment where those are saved as I never used them myself (maybe ~/.local/share/kmail2/ as well). Although, IIUIC the problem only occurs with certain mail folders, so that probably won't help then.
