Description Stephan Sokolow 2011-12-22 03:07:33 UTC 
Some applications and scripts still use $BROWSER as their primary means of allowing user customization.

However, xdg-open makes no attempt to guard against self-calling when falling back to $BROWSER.

This makes it dangerous to set BROWSER=xdg-open in order to portably integrate older applications with GUI-based mechanisms for specifying the user's preferred browser.

I looked over the code, and while the possibility of hitting this case is small, it's not exactly zero either, so...
