Openoffice (other zipped file formats) vs Nautilus 2.5.5

[Khairil Yusof]

I've noticed this with recent Nautilus releases.

It will "correctly" detect that some compressed file formats such as
OpenOffice and Dia as zip or gzip archives.

Is there a way to override this file detection capability for specific
files (eg. extension over file format)?

I can't seem to figure out how to override this besides registering
OpenOffice/dia as applications for zip and gzip files.
