Errors with rpm-4.0-26mdk

[Sven Herzberg <herzi@xxxxxxxxxx>]

When updating rpm's I get the following error message:

[root@snoopy RPMS]# rpm -Uhv sawfish-0.39-3mdk.i586.rpm --nodeps --test
Speicherzugriffsfehler(core dumped)

Notation: 'Speicherzugrifffehler' is german for something like 'memory 
access error'
This does not use to happen with every rpm but I know that it does with 
all rpms replacing files from other installed packages (... conflicts 
with file of ...). And a lot more
Thanks

ps: The issue to mount with -o biosize=13 did not work.
