Find fails to find a word at last line.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open or create a document using gedit.
2. Go to last line and type in any column a word that is unique in the text.
3. Move the cursor before or at beginning of the word typed.
4. On the main menu, select "Search" and then "Advanced Find/Replace" to open 
the search dialog.
5. In "Find what" field, enter the word that was typed in the text.
6. Set only the option "Match whole word" (to avoid partial matches) and unset 
all others.
7. Select "Forward" for "Direction" and "Current Document" for "Scope".
8. Hit the Find button.

What is the expected output? What do you see instead?
The word searched should have been found. Instead, a dialog opens with "Nothing 
is found." message and if the cursor was at a previous line, it moves to the 
last one.

What version of the product are you using? On what operating system?
- advanced_find-0.5.3.tar.gz;
- up-to-date Fedora 14;
- gedit-2.30.4-1.fc14.i686;
- python-2.7-8.fc14.1.i686;

- gtk2-2.22.0-1.fc14.1.i686;
- pango-1.28.1-4.fc14.i686.
