Bug#923311: steam: Client crash

[Moshe Piekarski]

Package: steam
Version: 1.0.0.59-4
Severity: important

Dear Maintainer,

On aproximatly 60% of attempts to login to steam using the client system freezes (Ctrl+Alt+Fx doesn't work, Sysrq appears to have no affect, and the xterm with journalctl -f running shows nothing).
This seems to be more common when my system has been running for a while.

Thank you for your time.
