I really like the income by security report. For people that have securities that are paying a lot of dividends or interest it gives a much better picture of what your actual return on investment than other reports that only show prices.
But I have run into a number of bugs, which seem to be limited to the legend.

Bug #1: When selecting to Subtotal by: Account one my accounts displays a blank in the legend.
Bug #2: Cash security type is wrong in the legend. Note that this is in a regular savings account with the intent set to investment.
Bug #3: from above just changing to Include all dates, the legend got "wiped out" and only includes "No Type" (cash), but not Mutual Fund:
