Description of problem: I have heard several anecdotal reports now of documents being opened from email messages using 'Open in Xxx', edited and saved, and then later sought. Of course, they are gone since the temporary file that evolution created has been deleted. Evolution should just make the temporary files read only, which it creates for applications to open attachments. Version-Release number of selected component (if applicable): All
This is the sort of change that I'd only want to pull in via upstream and even then, it's not going to be overly useful (most people will just take the "overwrite the file?" dialog and just say yes without really reading it).
