Bug 1110746

+++ This bug was initially created as a clone of Bug #1106385 +++

Description of problem:
A custome report is generated for the dates between From and To.
If the range is illogical, a blank search resolt is being returned, but a search still occures. The ranges here should be protected, so for example a user should be able to insert
From: Steak and Kidney Pie
To: -1000-01-01
which returns a 500 response.

Version-Release number of selected component (if applicable):
python-django-horizon-2014.1-7.el7ost.noarch

How reproducible:
Always

Steps to Reproduce:
1. go to Resources Usage > Daily Usage
2. select as range Other
3. Enter From: something silly
4. Enter To: something sillier

Actual results:
Something Went Wrong message.

Expected results:
a warning saying that ranges are not valid
ranges should be protected. a good range here might be from EPOC to 2025 and date format only.

I can not reproduce it. 
The error message is: Error: Invalid date format: Using today as default.

I can reproduce it on the version that I mentioned. What version are you testing it on?

Nah. scratch that. 

Reported upstream, raised prio.
Amit, thank you for insisting here, you're absolutely right.
