[Thinlinc-technical] firefox on Linux broken by b4918,b4972?

[Darrel Hankerson]

firefox 26 (and iceweasel 24) on Linux reaches "loading" and then stalls
forever on 4.1.1-4339 with the May security updates b4918,b4972.
firefox 29 on Windows works, and a test server without the May patches
works.

I'm not certain that the breakage started with the patches.  firefox 26
on Solaris and iceweasel 24 on Linux was working.

Is this known or known to be working in 4.2?
