It's lame that the "What should mozilla do with this file" dialog doesn't let me just type "xine" into the "Open it with" field. Instead, it makes me have to figure out whether that is "/usr/bin/xine" or "/usr/local/bin/xine" or "/usr/X11R6/bin/xine". Mozilla should let me enter just the *name* of the program, and only complain if that program does not exist somewhere on $PATH.

setting it from the preference dialog works... it sets the pref blindly. When the pref is actually used, nsExternalHelperAppService::FillContentHandlerProperties calls GetFileTokenForPath, which looks through the path. the helperAppDialog sets preferredApplicationHandler directly without looking at the path.
