Ubiquity 0.5pre2 parser can't handle long text being pasted.

The new parser seems to have trouble handling pasted text when generating search results. I treat a bit more like a command line than a language parser, so when I tweet about a page, I usually paste a clip from it, then focus on the address bar and type:
tw <paste> this as <user>
Ubiquity 0.1.8 handles this fine, but the 0.5 parser is obviously trying to parse the pasted text and fails. This is a bit better than pre1, where the parser would spin out of control and lock up the entire browser, but it's still not allowing me to use the product with just basic commands. I understand that the new language parsing options are cool, but it won't help much if the basic cases don't work!</user></paste>
