[plasmashell] [Bug 359943] New: New FindIsoCodes.cmake file requires cmake >= 3.4

[Christian Butcher via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=359943

Bug ID: 359943
   Summary: New FindIsoCodes.cmake file requires cmake >= 3.4
   Product: plasmashell
   Version: master
  Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: Digital Clock
  Assignee: mklape...@kde.org
  Reporter: chrisb2...@gmail.com
CC: plasma-b...@kde.org

The new FindIsoCodes.cmake file introduced by commit
fea67bd2ae7549e88952ac6dbcf90392d0ee1458 to plasma-workspace uses the
'pkg_get_variable' function, which is first available in cmake v3.4.

Either the use of the function should be removed or the cmake version
requirement should be bumped (but it's a pretty big bump).

Reproducible: Always

Steps to Reproduce:
1. Try to run cmake in git-master plasma-workspace with a cmake < 3.4
2. CMake fails with 'Unknown CMake command "pkg_get_variable".'

[kwin] [Bug 358004] New: Kwin crash on closing matlab figures / closing matlab

[Christian Butcher via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=358004

Bug ID: 358004
   Summary: Kwin crash on closing matlab figures / closing matlab
   Product: kwin
   Version: unspecified
  Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
  Keywords: drkonqi
  Severity: crash
  Priority: NOR
 Component: general
  Assignee: kwin-bugs-n...@kde.org
  Reporter: chrisb2...@gmail.com

Application: kwin_x11 (5.5.90)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.3.0 x86_64

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

Matlab command line entry

figure();
close(gcf); % This line closes the active figure

reproduces (almost) every time.

Backtraces are available (one probably attached to this report by KCrash)
additionally at 
https://paste.kde.org/pu8niuxq5 (figure closing)
https://paste.kde.org/pxwcosz7a (exit of matlab)

Using Nouveau drivers, output of kwin_x11 --replace is:
