IE user-agent with "toolbar" attribute detected as mobile

[mimmi]

I found a lot of user agents in my logs who looks like IE, but are detected as mobile (id: mowser_transcoder). See below for some examples..

I am using the PHP API 1.3.1.
Should this be the correct behavior?

This is not the expected behavior. I am looking into it.
