unity8-dash crashed with SIGSEGV in data()

[kevin gunn]

mako vivid #94

1) relatively freshly flashed (e.g. no OLA setup yet)
2) navigated to ubuntu app store
3) selected preview of app to install
4) selected the "install" button (which i expected would take me to system-settings to set up my account info)
this is when it crashed, i was able to have this happen a couple of times...altho, on the 3rd or fourth attempt it did not occur
