Subject: libkdecorations2-5: updating libkdecorations2-5 to 4:5.3.2-2 breaks kwin

Date: Wed, 19 Aug 2015 23:55:59 -0430

Package: libkdecorations2-5
Version: 4:5.3.2-1
Severity: critical
Justification: breaks unrelated software

I'm using kde plasma 5 from testing with kwin-x11.
After updating libkdecorations2-5 from 4:5.3.2-1 to 4:5.3.2-2 kwin crashes all the time. Mostly after entering your credentials it even doesn't manage to start up the desktop. After a while a message appears, that kwin crashed several times, if you want to change to an other window manager. The kwin version installed is 4:5.3.2-3.
The stacktrace is following:

Application: KWin (kwin_x11), signal: Segmentation fault

Control: affects 796184 + kwin

Can confirm that. The workaround is to download
libkdecorations2-5_5.3.2-1_*deb and
libkdecorations2private5_5.3.2-1_*.deb from
http://snapshot.debian.org/package/kdecoration/4%3A5.3.2-1/
and install that.

Problem is that it now is build against libstdc++ from this transition: 
https://release.debian.org/transitions/html/libstdc++6.html

It should have never been transitioned to testing.

Same here, marking the version accordingly so it is clear that this is a
new bug in 5.3.2-2 (although it is too late now).

I don't see the bug listed in the kwin BTS despite the affects. Possibly
because the kwin binary package doesn't exist. Marking kwin-x11 as
affected as well.
