Regardless of whether Orgs/Locs are enabled, in release 1.7.2 and prior, the OS Distribution graphic's clickable slices at times produce invalid search queries producing an empty search result.

Cases I have discovered seem to all be where the length of the label string is shorted with ellipses.

Examples:
os_title="SUSE Linux En..."
os_title="Solaris 5.10 ..."
os_title="Oracle Linux ..."

In addition, the graphic itself often produces multiple slices that appear to be identical due to the shortening that produces the problematic searches. I run Multiple versions of Oracle Linux 5 and 6 as the primary OS in my environment (111/180 systems). The OS Distribution Graphic shows four different slices all producing the same os_title="Oracle Linux ..." search query, leave me unable to identify which version the slice refers to.

Screen Shots of the Oracle Linux problem case are provided.
