ubiquity crashed with AssertionError in copy_all()

[returnofnights]

Binary package hint: ubiquity

I reported this and it got triag'd to bug #536981, it is NOT the same problem, I even added the exit 0 to the suggested file with the exact same results.

mine got passed the initial problem and ubiquity would crash on the Copying Files screen after the partition's were made. This appears to be a problem with permission handling (it occurs every time) it's strange that the ubuntu beta 2 release is able to install fine with this situation, maybe it's something else they do and don't share with us remix creators.
