I can't reproduce this behaviour with current SVN. I suspect it was fixed in the meantime, since there was some work on the text tool (e.g., during the Summer of Code project).
But when entering numbers manually in the entry field, it responds to every keystroke, which is very unconvenient and annoying. For example, enter 20, then delete the '0' --> text size jumps to 2; or if you accidentally enter another number (say, 3) it jumps to the huge size of 203. Instead, the entry field should only react when return is pressed.
