[Tlf-devel] tlf segfault

[Thomas Beierlein]

Hi,

Tlf segfaults immediately after start on some machines here if started 
with 'tlf -n' and if SPOTLIST is activated in logcfg.dat (as installed by
default as example).

Found the reason in cluster_bg.c where in case of an empty spotlist tlf uses 
some negative indexes for array access (around lines 460..490) . Bummer!

The following diff fixes the problem. I hope Rein can integrate the patch soon 
and release a fixed version.
