Code review comment for lp:~craighewetson-deactivatedaccount/bzr-explorer/shorten-refresh-time

Craig, I think I know how to not block Close button.
You should not execute self.do_refresh() immediately, instead you should send additional signal to yourself with

QtCore.QTimer.singleShot(1, self.do_refresh)

The timer will start refresh once all other signals will be processed, as I understand. So buttons should be activated and won't blocked by refresh.

Craig, please test this change and say if it works as expected without patching QBzr.
