r73036 is affected
Microsoft Excel Viewer 2007 installer reports negative required disk space of "-789054976bytes".
happens only if german localization is selected during ros setup, when english ros setup is selected it's fine.
The results seem to be biased sporadically additionally, be careful when interpreting therefore the following test:
(IIRC using r73036 also "OpenOffice 126.96.36.199" required "0bytes", so I guess we have a structural issue here)
Maybe a very hard to solve ticket...
