Bug#712017: steam: Steam crashes whenever it tries to load a page with Flash content

[lex]

Package: steam
Version: 1.0.0.39-1
Severity: important

Whenever I try to open a page in the store with any content in Flash, Steam
crashes.
It just quits the program. I've tried to install the flashplugin-nonfree
package, but
it did nothing. Is there a way to configure Steam to just work with Gnash or
Lightspark?
Or just not display the Flash content and just work without?
