Please describe the problem:
I created a multicolumn report with two columns and two rows. I inserted two Income Pie charts in the first row and two Expense Pie charts in the second row. I saved the custom report and restarted GnuCash. Now when I try and run the custom report it says:
>> Report Error
>> An error occurred while running the report.


Steps to reproduce:
1. Create a Multicolumn report and insert few piecharts
2. Save this custom report and restart Gnucash
3. Try running the custom report from 'Reports -> Custom -> Custom Report Name'


Actual results:
A new tab with the report name appears. But instead of the report, it contains an error message:
>> Report error
>> An error occurred while running the report.


Expected results:
The report I created.

Does this happen every time?
Yes
