Description Artem Anisimov 2010-01-13 08:11:53 UTC

Application: kwin (4.3.90 (KDE 4.3.90 (KDE 4.4 RC1)))
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.33-rc2 i686
Distribution (Platform): Slackware Packages

-- Information about the crash:
Beginning with KDE 4.3.90, KWin started behaving strangely to me: all dialogs that used to be small (open/save save, prompt for wallet password, etc) now get opened maximized and without border.

When I try to select "No border" in menu of such a window, I consistently get KWin crash.

The crash can be reproduced every time.

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Are you using the plasma netbook shell?

> Are you using the plasma netbook shell?

In systemsettings/desktop/workspace I tried yesterday to set Netbook to see if looks better on the 12" screen of my notebook, so probably, the answer is yes, I do use.

"Probably" goes here because right now I looked at that option and it showed Desktop.

As far as I remember, KWin crashed soon after applying the "Netbook" setting. However, I am not sure that netbook shell is the only cause of that crash -- while configuring effects and other options in systemsettings/{appearance,desktop} I experienced frequent crashes of KWin. Unfortunately, yesterday KDE 4.3.90 was compiled without debugging info.
