Cannot delete folder

[Yves Goergen]

That must be a wrong observation. ".Trash.Test" didn't exist, because 
".Test" should be moved there. That looks expected to me. ".Test" itself 
did exist and the log didn't say anything else.

But I've already found the issue. My maildirs (created by a system 
management script) had unexpected permissions. While everything worked, 
Dovecot denied deleting such a folder because it didn't have the exact 
same permissions, albeit both accessible.

Well, there is the first error, too:

yg/.Test doesn't exist yet

is it possible, that you are subscribed to a non-existant folder?
Thunderbird (or some versions anyway) will display any subscribed folder,
regardless if it exists or not.

Dovecot fails to both delete or rename non-existant folders.

Checkout the local file "subscriptions" in your mailbox storage. (Close
any mail client before).
