Description of problem:
I'm getting ISE when filtering users in channel management page -> managers


Version-Release number of selected component (if applicable):
spacewalk-java-2.1.148-1.el6.noarch


How reproducible:
always on one SW I have tried


Steps to Reproduce:
1. In webUI go to Channels -> Manage Software Channels -> <some_custom_channel> -> Managers
2. Write "hello" into search bar and press "eye" icon


Actual results:
ISE


Expected results:
Should filter (no matches in my case as I do not have "hello" user)
