Ok I checked a bit the problem, since we didn't break compatibility
before we haven't any libkexiv2.so.1, and that's why we can't updgrade
to libkexiv2 0.1.5 _from_any_previous_ one without rebuilding the 
applications that need it.

Yep, unfortunately it is. And since we have that problem in cooker we can di that
without care, but this problem makes me thinking we should pay attention next
time to avoid that...

Cheers,
