Segfault while manipulating stacked barchart report

[Rik Harris]

I got a one-off segfault while resizing (in the Options, from 400x400
to 1000x800) the "Expenses Over Time" stacked bar chart with 24 months
of monthly data.  I was using CVS from Jan 13.  I can't reproduce it in
either the Jan 13 CVS or today's CVS.  I understand this is completely
useless (which is why I'm not logging it with bugzilla), but it might
be another data point if this sort of problem happens with someone else.

Here's what was printed to the console:
