Hey Wulschke, thank you so much for your prompt reply!
You're absolutely right that the owner of Temp is wrong. However I put that wrong unwittingly when trying to solve the problem of bad permissions. That's because I did a
chown 750 Temp instead of a
chmod 750 Temp, ups! That's solved now:
8 drwxr-x--- 2 xinelo xinelo 8192 2006-05-28 18:32 Temp
However the message still appears, the same as before chowing the Temp directory. Any other clues? (it would have been too easy otherwise

)
Thanks a lot again, and have a great Tuesday too!
PS Thanks too for your help with the updating of the package.
