I wanted to add a new Email-Account to my existing IMAP-Account and did it the wrong way.
Now everytime i start KMail it says
“Im E-Mail-Programm ist ein schwerwiegender Fehler aufgetreten. Das Programm wird beendet.
Die Fehlermeldung lautet:
Could not create collection trash, resourceId 4”
and crashes KMail.
I tried to purge KMail and reinstall it, but that does not help, beaus it is not completly purged.
