 We need to redesign QError. I could give it a try, but quite frankly, I
don't know how do it good enough..

 Markus has worked more on error handling than me though and I think he's
the best person to do it, but he's busy at other things atm.

 Note that major work is design, not code churn (could turn out into an issue,
but I doubt it).
