Description of problem:

When I try to promote a published content view that has RHEL 5Server i386 RPMs, I see a spike in memory consumption for foreman where a thin process uses 100% CPU resources. Seems that the issue is with the media name being automatically generated in foreman which for some reason has trailing spaces (and a double space). I've been told by @inecas that the regular expression used by both the API and UI don't seem to be validating this field.

  value: SimpleOrg/Dev_Env/PublishedRHEL532 RHEL  Server 5.9 i386
  regular expression: /\A(\S+\s?)+\Z/

Once the thin process consumes 100% CPU and 15 GB of my 16 GB available, the Foreman UI becomes inaccessible and the only way to "fix" it is to restart foreman.
