Comment 1 Hugo Pereira Da Costa 2012-05-12 09:12:42 UTC

Can't reproduce.
(Qt 4.8.1 and kde from master)
I suspect either a problem with Qt4.8.2 or some inconsistency between library path and plugin path (since you compiled from source)
Please make sure that the right plugins kwin_oxygen_config.so and kwin3_oxygen.so are loaded by system settings (right path should be $your_local_install/lib/kde4/, and not, e.g. /usr/lib/kde4/)

Comment 2 Christoph Feck 2012-05-12 12:09:23 UTC

On my system, there is only a single installation of Qt and KDE, both compiled from source, so it cannot be a mismatch of paths.

Comment 3 Hugo Pereira Da Costa 2012-05-12 12:13:04 UTC

... same here.
So ... Qt4.8.2 ?
(fact is: crash happens in a Qt method indeed)

Comment 4 Christoph Feck 2012-05-12 12:31:25 UTC

I recompiled all of kde-workspace, and can no longer reproduce. The problem probably was that I yesterday updated/compiled kwin alone (which includes the decoration), without rebuilding oxygen library. Since there is no binary compatibility garantuee across different compilations of different parts of kde-workspace, this bug is invalid.

Comment 5 Hugo Pereira Da Costa 2012-05-12 12:53:04 UTC

"The problem probably was that I yesterday updated/compiled kwin alone (which includes the decoration), without rebuilding oxygen library"
yes most likely that's it.
that also can create inconsistency lib vs plugin.
