There is something else I want to mention. Another user on this computer launched linux steam client sucsessfully before me and even play TF2. After that he closed steam client and logout. My issue begins after that.
I believe I see why the client is crashing and an upcoming client will have a fix for that. It should also fix the problem where Steam doesn't work after being run by a previous user, so it should fix your issue.
This should be fixed in the latest beta client.
Nothing extracted yet.
I'm trying to recover my account but steam crashes.
I've tried several times with account name, email and product code.
I'm entering account name, clicking "Next", then "Steam - working" window appears, and after some time it all disappear.
I'm using Kubuntu 64bit.
