StarCraft II on Ubuntu 12.04 crash

After updating to Ubuntu 12.04 StarCraft II started crashing during login with an “ACCESS VIOLATION” error.
I did a quick google search and found this post about it.

Basically the workaround is to turn off a kernes security feature by executing:

sudo sysctl kernel.yama.ptrace_scope=0

You can turn it back on by executing:

sudo sysctl kernel.yama.ptrace_scope=1
