"Folder History" in revision browser does nothing
Created originally on Bitbucket by orangy (Ilya Ryzhenkov)
Win7, thg-2.6.2 with Mercurial-2.4.2, Python-2.7.3, PyQt-4.9.1, Qt-4.8.0
Actual: Use "Browse at rev" to open repository browser, select folder, right click, select Folder History. Nothing happens.
Expected: Hg log viewer for folder (all files in folder) is displayed.
