Hi,
I'm playing with plasma5 from github, but kwin crashes pretty much
immediately. I managed to produce this backtrace:
[mark@markspc /usr/home/mark]$ lldb /usr/local/bin/kwin_x11 -c
kwin_x11.core
(lldb) target create "/usr/local/bin/kwin_x11" --core "kwin_x11.core"
Core file '/usr/home/mark/kwin_x11.core' (x86_64) was loaded.
(lldb) bt all
