Ubiquity Verb Suggestion changes unnecessarily

[Bhagwad]

I find that in some cases, Ubiquity changes the verb suggested in mid
word even when I explicitly start typing the full name of the verb.
Here's an example.

Command Name: insert-link : Used to insert a link from History .

I type: "insert-link ra" (Till now all fine. Ubiquity displays the
verb "insert-link" with suggestions from my awesomebar like RAID etc -
because of the "ra")

The moment I type a third character making it "copy-link rai", the
suggestion verb suddenly changes to "note-in-reader" and the "insert-
link" verb is nowhere in sight even if I make the suggestion list 10
entries!

Why is Ubiquity doing this? I'm calling a command by its full name at
the start - why should it think I want a different verb?
