Kdenlive ppa ... use the appimage... ;)

[Harald Albrecht]

So, tested also the stable ppa and got the same crash.

Luckily, even the current AppImage 18.04.1 correctly loads my existing 
17.12.0d project.

And I don't want to throw away my recent project that's just three weeks 
old, because it was a company-internal demo video which will now be 
expanded into a (still company-internal) instructional video. I don't 
thrill on throwing away carefully done stop-and-go screencast cuts, more 
so as most of my projects aren't fire-and-forget projects (no pun in 
that, not at all), but usually get fixed and updated when they contain 
errors which get spotted only after first release.

Best regards,
Harald
