- Operating system set to new value
  Windows XP
- Steps to Reproduce set to new value
  In PHP, create a new MgQueryOptions object and call SetFilter with some non-ascii character like %fe decoded.
- Platform set to new value
  PC
- Defect Severity set to new value
  High
- Description set to new value
  Setting a filter on an MgQueryOptions object can cause the web tier to hang if the filter string contains invalid characters.

This happened because I was passing a filter string from a browser that looked like '<field> = "%fer%"'.

When PHP decoded the string, it decoded %fe as a character (some wierd p thing) and then SetFilter caused the process to go off into outer space.

The desired behaviour would be to generate an exception.
