Armor paint crashes when adding a material from the cloud

[WKolisnek]

ArmorPaint 1.0 alpha-65e7d8, Windows

Issue description:

When I try to add a material from the cloud my armor paint full crashes then closes

Steps to reproduce:

I drag a material from the cloud into my material layers, armor paint then crashes

[WKolisnek]

Armor paint now seems to be crashing when I try to open a folder that has a material in it on the cloud? Such as going to my user>materials>armorlab, upon opening the armorlab folder the app crashes

Cloud import should be resolved in the latest build, thanks for report!
