Had this issue for the last two weeks on Ubuntu 13.04 and Linux Mint 15 while trying to navigate trough Store and Community pages inside Steam client. Looks like it's a problem with Flash Player plugin on x64 systems. Solved it trough these steps:

-Download the Linux x86 .tar.gz of Flash Player at http://get.adobe.com/flashplayer/otherversions/
-Extract only the "libflashplayer.so" to ~/.steam/bin32/plugins (it may be necessary to create the plugins folder)
-Restart Steam

Hope it works for you!

I have the same crash on Ubuntu 13.04, it occurs every time I navigate to the "Emergency 2013" page (I want to buy this game, I realize there is no Linux version for it).

There is one additional line from alsa_output.cc.

The fix posted by rfortunatti works for me (i.e. downloading libflashplayer.so). Maybe the crash is because I had the "Automatischer Videostart" (video auto-play) feature enabled?

Sorry I’m late to this. It appears to be a duplicate of #2417, videos are causing crashes in the store browser. Please comment/watch that other issue.
