Mailbox inaccessible after setaclmailbox with invalid identifier

After running `setaclmailbox some/mailbox "group:name with spaces" all`,
all attempts to access the mailbox in any way either result in an
"Invalid identifier" error message, or can't even find the mailbox.

deleteaclmailbox with exactly the same parameters as set doesn't help
(same "invalid identifier" error); cyrreconstruct doesn't even find the
mailbox. Deliveries are deferred as well.

Any ideas how I can recover the mailbox without rolling back the whole
server to an older backup?

(Cyrus 2.5.10 on Debian stretch, if that matters.)
