Description of problem:

Filing a new RHEL7 kernel bug without selecting a kernel sub-component results in a traceback error (below).


Version-Release number of selected component (if applicable):
Current version of redhat bugzilla as of August 2014.

How reproducible:
Always.

Steps to Reproduce:
1. Start filing a new RHEL7 bug.
2. Component: kernel
3. Do *NOT* choose a sub-component for kernel.
4. Fill in other details
5. Submit -> traceback error.

Actual results:
You get a traceback crash instead of normal warning about missing selection in kernel sub-category.

Expected results:
Works normally, so you get a normal warning about missing selection in kernel sub-category, when it's a required field.
