duti -x and multiple apps exported uti.

[grylem]

If 2 or more apps declare uti for files some duti's command dont work.
for example:
duti -x ape
Failed to get default application for extension 'ape'
mdls file.ape - com.monkeysaudio.ape
duti -u com.monkeysaudio.ape
description: Monkey's Audio Lossless Audio File
declaration: {
UTTypeIdentifier = com.monkeysaudio.ape
UTTypeDescription = Monkey's Audio Lossless Audio File
UTTypeTagSpecification = {
public.filename-extension = [
ape
unhandled value
]
}
UTTypeConformsTo = [
public.audio
unhandled value
]
}

duti -e ape
