[kdenlive] kdenlive crashes in multiseat configuration

[Zenny]

Hi,

I am trying to run kdenlive inside a multiseat computer (two kvms
meaning separate set of kb+video+mouse connected to the same computer
Ref. https://wiki.ubuntu.com/MultiseatTeam/Instructions) .

Kdenlive runs fine in seat0, but crahes in seat-1 and outputs error as
follows (melt in command line works alright, so it does not seem a
mltframework issue):
