  In this paper we suggest a new source of perturbative decay of the KPV-state,
which might have consequences for the viability of the KKLT-construction. The
results do not rely on any direct enhancement of the decay due to flux
accumulating on the anti-brane in transverse space. Instead, we note that the
system can lower its energy through a sequence of NS5-configurations all the
way to the true vacuum, without encountering a barrier, if we allow for
clumping of screened charge in space time. The clumping can possibly be a
parallel to the Gregory-Laflamme instability of black branes. The results are
obtained at large $p$, but for $p/M$ arbitrarily small. It is furthermore
argued that the results extend to cases of few or single anti-branes where
quantization becomes important. We believe that it is important to investigate
this possible effect further to judge whether there are any fatal consequences.
