I sas re-installing a 15.04 x64 ISO image earlier and I had the above freezing problem with ubiquity.
I was reusing my existing partition structure, keeping the /home partition but formatting the others.
I found that removing a /var partition and formatting / and /usr partitions allowed the installer to move to the copying files sections of the install.
