No longer reproductible
* latest version of KDE on kubuntu 22.04, 

Now, moving a folder via mouse moves the folder but it does not appear to have
moved until after a restart of the system. Restarting Kmail alone does not seem
to move it.  I didn't try akonadictl restart, so that might do it.

In any case, it doesn't segfault and crash now.

--- Comment #25 from Richard Johnson  ---
Latest tests:
* December 2020
* kubuntu 20.04  
* Kmail 5.13.3 -- not sure of QT version (but it's the default)
* Using postgresql (moved from mysql because of repeated table corruption)

Opened a maildir that was not the default ~/.local/share/local-mail, attempted
to move folders.

1. Unable to select more than one folder at a time to move.  (Not sure it's a
bug.)

2. Moved a few folders, and then akonadi crashed.  This requires a kill and
restart of both kmail and akonadi in order to recover.  It is repeatable.

I have not been able to get a good stack trace on it yet, but suspect that
moving large directory trees risks either a buffer overflow or a race
condition.

My wish to apologise - the crashes I've recently reported due a segmentation
fault and an abort, do not seem to be related to this issue.
 Bug Reports 425936 & 426863.

Maybe my memory is failing - old age - really - born 1949 . . .

And another one. This happens quite reliably at the end of each move.
Fortunately, the move itself seems to suceed.
