screenshot illustrating the issue

The title might be confusing, but to be more precise, for file extensions
associated to Office Application (and even others) I get multiple "open with"
proposals, all referring to the same Office component (screenshot illustrates).

The issue seems to lie in the way wine registers the file mime-types. For a
.ppt file, i.e., I should get only one "PowerPoint" entry in my open with
dialog.
