Crashes with 6106 Segmentation fault under linux, demo worked

I'm not sure if this double the "Doesn't work in Linux"-thread but I can not play the game anymore, because it crashes with

The demo worked without a problem. I could play the full version 1x. I completed the final pluto-level. After the level I was told that I received several archiments (the ones I got from the Demo) and I saw them also in the steam-client. Then I started a run on the outer-space-endless-level for some minutes before I died. Then I tried to restart the level and the game crashed and my archiments in steam were gone again. Now the game crashes shortly after I start.

The following workarround works for me: Click right on the game in the libary, select "Properties". Disable the "Enable steam community in the game"-checkbox. Ok.
