In the meantime I found out, that my recent 20091006-2 package did not
run munchlist over the mwl file (don't ask me why).  After doing this
again, buildhash no longer has problems building the hash.
I just uploaded a fixed igerman98 20091006-3 to the archive.

So I think that the severity of this bug report can be decreased.
Nevertheless it is IMHO a bug that buildhash can run into such a
trouble that ispell segfaults when it uses the dictionaries...

Tschoeeee
