Description Anton Arnold 2020-04-03 10:04:18 UTC

I experienced some syncing problems with an IMAP account where new messages did not arrive even by manual sync and tried restarting akonadi.
The initial problem did not happen again, but the unified mailbox does not contain the stated IMAP folder and exception is thrown apparently in ItemQueryHelper::scopeToQuery#L156
