So, after few hours of instruction-by-instruction tracing I was finally able to find the reason of crash. It was induced by homebrew. After installing `xulrunner` via homebrew, there were `nss` and `nspr` packages symlinked into `/usr/local/lib`. For some reason Firefox dynamic linker picked them up TOGETHER with same libraries at the build directory. Spotted this accidentally when I noticed base addresses differ for what I'm stepping through, and that module loader shows there are two instances of library loaded at different paths.

To fix crash, do the following at the shell:

    $ homebrew unlink nspr nss

Wow. Well spotted!

Soliciting the opinion of our low-level experts - is this something that is FF's fault, or should it be resolved on the end of the Homebrew folks?

Will followup in the other bug.

I think it's ABP who's trying to open the nss from homebrew:

It is kinda related to bug 593484 again.
