Given the backtrace ends up with many cyclic calls into JavaScriptCore I would 
tend to think it's related more to QtWebKit than KWebWallet.

In a similar case with KHTML/KJS, the problem was due to using -ffast-math, 
which caused a miscompilation of some of the JavaScript internals (which are 
highly optimized and so sensitive to optimization bugs). -ffast-math shouldn't 
be a default optimization option (I think even -O3 doesn't pull it in) but 
make sure it's not in use.
