iLifeMedia browser works erratically in Mail.app

The problem occurs for quite a long time: when I press the pic icon at the top right corner of a new message (iLife Media browser's icon) the media Browser's window pops up with iPhoto not letting me to expand it's structure (Events, Faces, Photos etc). Besides that I see Photo Booth icon in that window though I don't recall any of my actions to add it to the list of options to select from. I did number of tricks trashing iLife Media browser's, Mail's, iPhoto's caches, repaired iPhoto Library permissions to no avail. Just yesterday I managed somehow to make it work as expected but today it renewed again! Why is that happening? Is it fixable?
