We finally traced it, after isolating which set of changes produced the 
error. Turns out the throbber definition from nautilus-shell-ui.xml 
(<control name="ThrobberWrapper" behavior="pack-end"/>) had been 
duplicated into nautilus-directory-view-ui.xml. Removing the duplicate 
solved the problem.

Thanks for the help.
