Sometimes I receive Word documents by email with MIME type application/x-ole-storage. Evolution does not offer 'Open in OOo' as an option for these, unless I manually configure it to do so.
Actually they're not received as application/x-ole-storage; Evolution was lying to me. It was actually an application/octet-stream. Looks like it's an Evolution bug.
This got worse with FC3, which have gnome 2.8/evolution 2. Even those files which are correctly associated in gnome cannot be open right from evolution - you got to save it and click it twice. This is true specially for powerpoint files. like (in portuguese): anexo Microsoft PowerPoint presentation (blabla.pps) - the only option I have is to save it. Maybe should I fill a different bug as there are so many differences between evolution 1.4 and 2?
Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match.
Closing per previous comment. Please reopen and give more information if the problem reoccurs in FC4 or FC5.
