nautilus crashed with SIGSEGV in g_cclosure_marshal_VOID()

This is from the 2nd use of the new nautilus bookmark quicklists in the unity launcher's "Home Folder"

Caused here by -
Opening an orig. nautilus window from the quicklist, opens fine.
Closing that window, then trying a new quicklist entry, crash occurs

After reopening nautilus quicklists become non-functional - .xsession.errors show -
