Incorrectly formatted commit message causes dvol log to fail

[brendan-donegan]

Making a commit with a badly formatted message causes dvol log to traceback as shown below. Admittedly the commit message here is somewhat deliberately misformatted - I would need to do a bit more investigation to see exactly what formatting causes this.

Update: I can reproduce this now with as simple a message as:

dvol commit -m "Clean state worth £30"

then running dvol log
