If you create an ez content package with a very long name, eg: toto_cutugno_le_zenith_forum_di_assago_hollywood_bowl_hammersmith-1.0-1.ezpkg, the setup wizard allows you to create it.

But the extraction fails - at least on windows, with error msg:
[ Oct 18 2011 13:33:16 ] [::1] eZFileHandler::copy:
Unable to copy directory var/storage/packages/local/toto_cutugno_le_zenith_forum_di_assago_hollywood_bowl_hammersmith/ezcontentobject, use eZDir::copy instead

Note: content seems to be created, just not 100% of it

Tested on windows.
