If I open ports 8009 and 8010 for Chromecast support, shortly after clicking around in Chromium it crashes. When I close these back up, everything works fine. I imagine if I unplug my Chromecast devices Chromium might also stay running. Crash information from GDB (I do not build with debug symbols): Thread 9 "Chrome_IOThread" received signal SIGSEGV, Segmentation fault.
