           Summary: "Retrieving Folder Contents" hanging without showing
                    content
           Product: kmail2
           Version: 4.7
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: message list
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: arthnr at gmail.com


Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

Instead of showing the content of a message, it shows "Retrieving Folder
Contents" screen forever. Starting the program from terminal it shows
"kontact(5365) MessageList::Core::ModelPrivate::findMessageParent: Circular
reference loop detected in the message tree". Only some few old emails are
shown correctly after a while and not always.  Mails are apparently fetched
correctly (via POP3), but set filters are not applied properly.

Reproducible: Always

Steps to Reproduce:
It started one day after launching the program, and then always (except once).
Just open a message folder.

Actual Results:  
What described above.

Expected Results:  
Show the content of the email.
