That's a question for the Evo team, I guess - it looks like it could be
trivially fixed by moving the folder.db somewhere else, or calling it
folder.index or folder.ibex.index or whatever Evolution traditionally
filters out.

To Evolution's credit, my 500MB folder.db binary blob didn't cause it to
crash - it showed up as a bogus local mail folder after about 15 minutes
of disk churn - but it did throw errors whenever it needed to pull data
for vfolders.

Also, it looks like old summary/index files aren't removed - does it
require both the sqlite database and summaries now? It increases disk
space consumption quite a bit.

I don't know if we ever guaranteed spotless downgrading, but yeah,
having that work would be a big plus - especially since users may switch
between distros but keep their home dirs.
