I obviously agree with this, and disagree with Jan, but I'd like to
avoid just repeating the previous discussion. The disagreement seems to
be about two things:

1) Any binary size increase is bad (as it affects cd sizes, etc)
2) The results of the MiniDebugInfo is not perfect, and
   there is a theoretically perfect approach. So we should not
   spend time/energy/space/bits/whatever on the non-perfect
   However, the perfect approach has other disadvantages
   due to being online/centralized, so I and others think
   its worth having both.

The increased space is clearly a project global wide question that
probably has to be decided by Fesco. 

The duplication of effort less so IMHO, as different people are doing
the work. If we don't do minidebug I will not be spending any resources
on the ABRT server anyway. So, not doing minidebug will not affect ABRT
positively, and doing it will not affect it negatively (in fact, it
might have a slight positive effect as it can use the low quality info
when offline). But still, as this is mainly a resource/project
management disagreement it might make sense to have Fesco look at it
