Could very well be. And please note that arora uses qtwebkit which isn't build 
from webkit source package (so probably clone && reassign should be needed)

Isn't sigbus usually related to unaligned accesses ?

and this is the web template framework, part of webkit, so yeah.
web template framework is at least also in khtml as in kde4, but at least the 
FastMalloc part is quite ... different.
http://websvn.kde.org/trunk/KDE/kdelibs/kjs/wtf/FastMalloc.h?revision=809424&view=markup
so khtml probably isn't relevant here.

but looking at JavaScriptCore/wtf/ ...

FastMalloc.cpp:1098:  uint64_t system_bytes_;
FastMalloc.cpp:1466:  uint64_t old_system_bytes = system_bytes_;

I'm a bit .. puzzled ?

I cannot get access over a application, how does it work?

From the preferences inside Office you should digit from the front-side bus of 
a floppy disk on a analogic wordprocessor.
