Git commit 17debc1d754f51a02254d5c3aabec9f756b6be1f by Jonathan Thomas.
Committed on 26/05/2011 at 19:21.
Pushed by jmthomas into branch 'master'.

Do not search if we are in the middle of a cache reload, like when the "Unmark All Changes" button is pressed.
This prevents a crash that occurs when the proxy model's source model is null during reload.
