            Bug ID: 305766
          Severity: critical
           Version: 4.8.4
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: SegFault crash and various error messages while
                    creating subfolders to 'inbox', moving them one level
                    up and moving mails from or to them
    Classification: Unclassified
                OS: Linux
          Reporter: xaver.xn at web.de
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: folders
           Product: kmail2

When I create a subfolder to the 'inbox' folder, when I try to move mail there
or from there, I get various error messages like:

>Lokale Ordner: Das Maildir „/home/xaverw/.local/share/local-mail/.Posteingang.directory/Versand“ für die Sammlung „Versand“ ist ungültig.

>Lokale Ordner: Der Zielordner ist ungültig: „Error opening /home/xaverw/.local/share/local-mail/.Posteingang.directory/Versand; this folder is missing.“

>Lokale Ordner: Der Unterordner „Personal“ kann nicht gelöscht werden.

(If it helps I can try to provide free translations).

Sometimes, this is accompanied by a crash of Kontact. I can't really test the
reproducibility as I can't jeopardize my mail, but these problems and crashes
have repeated. The last backtrace I got from KCrash was:

Application: Kontact (kontact), signal: Segmentation fault

Reproducible: Sometimes

Steps to Reproduce:
1. Create a 'inbox' (Posteingang) subdir
2. Move mail there and then to another folder
3. Move the folder one level up, to 'Local folders' (Lokale Ordner)
