the newest git version of minetest crashes my computer, it freezes, only restart helps, (using linux)

has anybody else the same problem??,
the previous version i had installed was 0.4.9

i updated my system now, i hope that this helps to prevent these crashes.

Hello
Strg+Alt+F(1-6) should work always
Then login
and enter "sudo killall minetest"
exit and return to X11 with Alt+F7
Have Fun,
JPR
