#19 — Install.applyGenericSetupProfile should not swallow exceptions

In some cases (see steps to reproduce), installing feedfeeder on Plone 3.x raises a KeyError exception with the traceback below. This exception hides the real exception behind it because Install.applyGenericSetupProfile swallows some exceptions (try: ... except: ...).

The traceback :
