           Summary: akonadiconsole uses 100% cpu
           Product: Akonadi
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: akonadiconsole
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: sven.burmeister at gmx.net


Version:           unspecified (using KDE 4.6.1) 
OS:                Linux

I had akonadiconsole open while I changed tha password for my email accounts,
i.e. akonadi could not access them anymore. I think that is what caused the
high cpu usage since there was no other obvious cause, i.e. even kontact was
not running.
