Please describe the problem:
The typeahead feature has stopped working properly in GTK+ 2.12.9 for me. Only a single character is accepted, but then the GtkTreeView kind of stops responding for a few seconds. The small typeahead window in the lower left corner then disappears and I'm allowed to enter a new character (but only one at a time).

This applies to Windows, I'm using the GTK+ 2.12.9 runtime binaries. The problem has also been reported here (independently from me): http://www.kksou.com/php-gtk2/PHP-GTK2-Help/228-GtkTreeView-search-on-windows.php

Steps to reproduce:
1. Create a treeview
2. Start typing to search for a specific item
3. Only one character is accepted


Actual results:
See above.

Expected results:
The typeahead window should be able to take the entire search string and the treeview selection should jump to the first match.

Does this happen every time?
Yes.
