Can you provide some screenshot?
I need to have something to start from.

There's already a screenshot at the URL field(http://i.imgur.com/qgKCvUj.jpg)

Please also get a screenshot of that same window in english.

I am reasonable certain these are string that come out of apt-pkg, so unless we run it through a latinstring somewhere it's probably a bug outside our reach.

Similar window when Muon is run with env LANGUAGE=en

I can't regenerate the same window on this system, so I pick another package(hime-anthy) on this case:
* Similar window when Muon is run with default LANGUAGE environment(zh_TW:zh_HK:zh:en) (*garbled* text)
* Similar window when Muon is run with env LANGUAGE=en (english)

I'm suspect there's a Unicode string being treated as latinstring here.
