• Distribution Debian
• Opted into Steam client beta?: Yes
• Have you checked for system updates?: Yes

exiting any game causes steam to segfault. Steam client will then not longer start back up until steam is reinstalled

Steps for reproducing this issue:

1. launch a game
2. exit a game
3. Steam becomes completley unlaunchable until after steam client reinstallation.

Valve, please fix.

workaround: i have made a really cursed bash script to completely reinstall steam. takes like 10 minutes to run on my system. so yeah, basically unusable.
