Based on the evidence that
1: when we backtraced the crash it was an unaligned access in 
libjavascriptcore (part of webkit)
2: webkit has a specific define in it's code already for whether the CPU 
needs aligned access
3: the aforementioned define was not previously set on sparc even though 
sparc is known to require aligned accesses
4: when jurij rebuilt webkit with a patch to set the aforementioned 
define on sparc seed built successfully
5: the earliest version of webkit/javascriptcore with which I have 
reproduced the issue is 1.6.1-5

I am reassigning this to libjavascriptcoregtk-3.0-0 1.6.1-5, retitling 
it, marking it as affecting seed and replacing the help tag with a patch tag

Webkit maintainers can you please upload Jurij's patch.
