are you running klipper or glipper or a similar clipboard tool? This sounds kind of 
like a bad interaction we've experienced with these programs.

This happens to me and dean as well. Dean suggested that it's a recent regression.

Dean suggests it might be related to the message loop change.

is a mostly Default Ubuntu 9.04 installation.

I spent a while working on this today.  I am 95% sure that it's a regression caused 
by this recent change:

    Fix crash due to AutocompletePopup trying to draw the old results when they were 
no longer available.I introduced this regression when moving |result_| to the 
AutocompleteController; the specific problem was the 
"result_.CopyFrom(latest_result_);" line I added when handling the synchronous 
messages being available

Assigning over to Peter.  When I revert this change locally, I cannot reproduce the 
truncation.  When I patch it back in, I can reproduce it very regularly.

I just confirmed this on Windows, build 17851.  I typed "std::vector" with the o-r-
enter keystrokes very quickly at the end, and I landed on a search for std::vect.  This 
is the same thing that is happening on Linux.

I've got the same problem,
when I'm typing fast (not pasting) asdf, it's searching for asd (I'm sure that I've 
pressed the last letter).
Other case, I'm typing 123 fast and after pressed Enter, nothing happen. It stops on 
proposing me 123[.com] ignoring my Enter.

Fixed in r17891.

Merge r17891.

Fix regression where hitting enter in the Omnibox would ignore recent editing.

Sadly, the only way I could find to fix this was a latest_result() accessor, because when the user hits enter, we really do need to use the very latest results.  This just highlights how more of this stuff should move to the AutocompleteController.

BUG=13428
TEST=Type "food.c" and wait for the popup to stabilize.  Then _very_ quickly type "om" and hit enter.  You should navigate to food.com instead of searching for "food.c".
