There may be a race condition between imap-mailbox-close in
asynchronous mode, and the code that send the UID SEARCH; the latter
code first check if the requested mailbox was already selected, and
then continue by sending the UID SEARCH command.  If the CLOSE command
was still pending when the code checked for the current mailbox, the
UID SEARCH code might get the wrong idea that the mailbox is still
selected.

Try toggling `nnimap-close-asynchronous'.

It should be possible to set a variable in the asynch
imap-mailbox-close mode to let other code know that it is closing a
mailbox, and add a check for that variable to `imap-mailbox-current',
although that is left as an exercise.

That did indeed solve my problem.  Thanks.

Ah, a well defined small task for the elisp newbie!  Thanks. :-)
