Re: "Open" on a folder starts VLC

[elpres]

Deleting the entry for VLC in the plist didn't help. I've also deleted
and forced Quicksilver to recreate Actions.plist, but this didn't help
either. There seems to be an issue with the way Quicksilver determines
the default application for folders, or perhaps VLC has registered
itself as a system-wide handler and this somehow overrides Finder.
Anyway, I ended up selecting Finder as target for "Always Open Type
With…" for folders, which solves the situation (thanks, Rob), which is
good enough.
