           Summary: Konquerer (and DrScheme) crashed when trying to drag
                    Konq tab outside of window
           Product: konqueror
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konq-bugs@kde.org
        ReportedBy: fbg111@gmail.com


Application: konqueror (4.4.2 (KDE 4.4.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
First time using Konquerer, was experimenting to see if its tabs work like
Chrome/Chromium.

I tried dragging a tab outside of the Konquerer main window to see if a new
window with that tab would be created.  Konquerer then crashed, taking DrScheme
with it in the same workspace/desktop (Workspace 2).

Other apps open in other workspaces didn't crash - Chromium and wget in
Workspace 1 and VirtualBox in Workspace 3 both stayed up.

Using Ubuntu 10.04 with kubuntu-desktop separately installed.

 -- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
