Pitivi segfaults

Hi,

the video editor Pitivi segfaults on my system. It starts up without problems, but whenever I click on the "New" button (welcome screen), it crashes.

Missing soft dependency:
- pycanberra not found on the system
    -> enables sound notifications when rendering is complete
Missing soft dependency:
- GnomeDesktop not found on the system
    -> file thumbnails provided by GNOME's thumbnailers
Missing soft dependency:
- Notify not found on the system
    -> enables visual notifications when rendering is complete

Is this a problem with Arch or should I report this upstream?

Kindly,

Re: Pitivi segfaults

Try to run like this to get some more info about what's happening:
$ PITIVI_DEBUG=3 pitivi

Until 0.96 is released you can try to use flatpak to run Pitivi: http://wiki.pitivi.org/wiki/Install_with_flatpak

Does that help?

Kindly,

Re: Pitivi segfaults

I remember now, the crash is caused by how it uses Gtk 3.20. It's fixed in the dev version of Pitivi. Try with flatpak.

Re: Pitivi segfaults

Hello,

Sorry to bump this out, but did it work ? And if it did, could you explain exactly how to use this fix ?
Thanks in advance,

Cheers.

Re: Pitivi segfaults

You can $ sudo gedit  /usr/lib/pitivi/python/pitivi/timeline/layer.py and remove the last two lines of the file.

Maybe try instead http://wiki.pitivi.org/wiki/Install_with_flatpak
