            Bug ID: 345582
           Summary: Virtual Desktops crash when using Wobbly Windows and
                    Switch desktop on edge
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: ugotsta at gmail.com

Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-10-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

With Wobbly Windows and "Switch desktop on edge" enabled, dragging a window to
a new virtual desktop crashes plasma.

To replicate:

1. System Settings > Desktop Behavior > Screen Edges:
for "Switch desktop on edge", select "Always Enabled " or "Only When Moving
Windows".

2. System Settings > Desktop Behavior > Desktop Effects:
enable Wobbly Windows.

3. Drag a window to the screen edge.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
