Build Identifier: 

The WebGL demo located at http://www.chromeexperiments.com/detail/mandelbox/?f=webgl crashes the browser while using software mesa (libOSMesa.so.6.5.3).

Looked a bit like Bug 589546 to me, but i was said to open a new one.

Reproducible: Always

BTW, this is on Ubuntu 10.10 and Netbook with Intel GMA 950 (no hardware WebGL).

I don't think that's the same as Bug 589546. That one was X errors, which OSMesa should not produce (since it's completely off-screen client-side rendering).

But, since your crash is deep into OSMesa 6.5.3 which we have long known to be buggy, this is a WONTFIX for us. If you want to further debug this, try getting a better backtrace by installing OSMesa debug symbols on your machine and running this in a debugger (GDB); or use a debug build of firefox and run with the environment variable MOZ_GL_DEBUG_VERBOSE defined and paste the end of the resulting log. In both cases, it's probably a better idea to report a bug directly to Mesa.
