        Hi,
Evolution's Maildir didn't support dots in folder names since the 
beginning. This had been added later. This migration is done only if 
the /path/to/maildir/root/..maildir++ file doesn't exists or denotes a 
wrong version. Its content should look like "maildir++ 1" (quotes for 
clarity only), where the '1' denotes the version number. This file is 
created automatically on start. It seems like your version is too low 
or the file is missing, for some reason (maybe file attributes?).

You seem to have this issue with your On This Computer folders, could 
you run these commands and post the result of them here, please?

   $ ls -l ~/.local/share/evolution/mail/local/..maildir++
   $ cat ~/.local/share/evolution/mail/local/..maildir++
   $ echo -n "maildir++ 1" >~/.local/share/evolution/mail/local/..maildir++

The last command will try to overwrite the version stored in the file, 
which will stop the folder hierarchy update. You may 'cat' it again to 
verify that the write succeeded.
        Thanks and bye,
        Milan
