gedit very slow to fully load text files larger then tens of megabytes

Binary package hint: gedit

1) lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04

2) apt-cache policy gedit
gedit:
  Installed: 2.30.3-0ubuntu0.1

     2.30.0git20100413-0ubuntu1 0

3) What I expected to happen is that when I open files tens of megabytes or larger, it does not take 10-30 minutes for it to load.

4) When I try to open files in the tens of megabytes or larger it takes a very long time to load.
