In the tracker view, if I search on a text field ('summary' for example) using a string containing '//', the search hangs (INTERNAL SERVER ERROR) and the tracker view becomes unavailable.
Steps to reproduce:
As a user,
1- Go to a tracker
2- Chose the normal mode of the report criteria
3- In the field summary (or any field of type string), enter the value 'aa // bb'
4- Click on the button 'Search'
