A new kind of type Ia supernovae?

It looks like type Ia supernovae may not be such good "standard candles" after all... here's one which seems to have had a progenitor above the Chandrasekhar limit.
Some possibilities: it could be the merger of two white dwarfs, or possibly a rapidly rotating white dwarf (this would enable it to be above the Chandrasekhar limit).
Might have a few implications for galactic distances.
