           Summary: Difficulty (and crash) when moving toolbars in all
                    sections
           Product: kontact
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: marcus at harrisonland.co.uk


Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Gentoo Packages

Testcase: Move the toolbars of each section in Kontact from the top to the
bottom. It can become tedious doing all of them individually, and often I get
crashes that give this backtrace:
