OO doesn't use MIME type to open document
1) get a MS Word document from anyware
2) rename it to "document" (without extension)
$ oowriter document
Result: OO opens blank document. If you rename back "document" to
"document.doc", oowriter opens it ok. This, for instance, breaks mozplugger.
Debian maintainers said that this bug is notreproducable in Sid
version. Could you please update OO backport to Squeeze version to
test if this bug is still exist? And to Sid otherwise.
