Fixing Save as Adobe PDF Crashes

There have been many reported instances of the "Save as Adobe PDF" workflow crashing regardless of application, but precious few workarounds or resolutions. In troubleshooting, I discovered that there were three instances of the "Save as Adobe PDF.action" in three different locations: /Library/Automator; ~/Library/Automator; and /System/Library/Automator. By eliminating all except the version in /System/Library/Automator, the workflow started behaving, and I was able to cut PDFs directly from the Print dialog.
