I noticed that it also happens when closing the last chromium-browser window:
WARN 2012-04-04 10:18:01 unity <unknown>:0 Unable to fetch children: No such interface `org.ayatana.bamf.view' on object at path /org/ayatana/bamf/application843378290
But in that case I'm getting only one line of warning (instead of three with pidgin).
