Chris, When you run Pcbnew from the command line, do you see a bunch wxLog messages with system errors? There is some system error logging that can occur in the one of the private objects wxDir uses. I'm not sure a broken symlink will trip the system error in question. If you are seeing log messages, that may be why Pcbnew is hanging and not the bad symlinks. There is a known bug with debug builds on Linux that will cause an application to hang when dumping output to the stdout when using KiCad to launch the application.
