vTiger 7.1 - Report hidden from List View if Primary module is Documents, and contains condition on Folder Name

Verified on demo.vtiger.com

If you create a Chart Report with the Primary Module being Documents, and give it no conditions - once created and saved when viewing the List of Reports it can be viewed correctly in the All Reports filter.

If you edit it and add a Condtion that uses the 'Folder Name' field (e.g. Folder Name = 'Default') then save the report and go back to List view, the report is no longer displayed in the list. It is possible to still access the report if you know the ID of it as you can change the record value in the URL (if on a blank system it will be record '26')

Taking the Folder Name condition out and saving again, will cause the report to show up in the list again correctly.

We have verified it happening if the Condition is in the All Conditoions OR in the ANY Conditions sections. Changing the condition to use a different field, and the report will show up again correctly.
