KDevelop crashes on code completion

Well, it's not completely sane to keep a local copy... If BDB is so bad,
it should be changed (sqlite?). But if it is not that bad, KDevelop must
be able to work with different versions. BTW, this is why we have kdelibs
and do not duplicate code everywhere.
 Anyway, Dirk said it will fix the crashes and he did. But there seems to
be another problem regarding the index creation.
 And removing -O3 is a workaround, not a solution. It was also not clear
if during your latest test you used 4.1 or 4.3.

Andras, who cannot test now, as has on the laptop KDE 3.4...
