            Bug ID: 346872
           Summary: Moving a window to another desktop
           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: ferhad at f-blog.info

Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I was using the desktob cube effect of Kwin. I've been using it since a year.

I have a fresh Kubuntu install with Plasma 5. I did my desktop cube settings,
and was running good. I needed to move a window to another virtual desktop. I
holded the window and moved it to the left of the screen. Different attempts
gave different results. One time, I got a bug report window only. On another I
lost all the close, full screen and window icons bar on all windows.

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".
