Description

When using host filter 'applicable_errata_issued > "10 days ago"' [0], I get error "undefined method `klass' for nil:NilClass" in WebUI and attached traceback. Happens for both filtering hosts in hosts list and filtering hosts while generating templates.

Steps to Reproduce:
1. Monitoring -> Report Templates -> Host - Statuses -> Generate
2. hosts: applicable_errata_issued > "10 days ago"
3. Submit

Actual results:
Error, nothing generated

Expected results:
Successfully generated, correctly filtered report

This can also be generated via rails console

> Host.search_for('applicable_errata_issued = "10 days ago"')
