This patch simply removes a space in a netscape -remote command that is executed by webbrowser. This space caused problems with certain urls, at least with netscape 7.2. For example, webbrowser.open_new('http://www.python.org') would file, though webbrowser.open_new('http://www.python.org/') would work.
Logged In: YES user_id=9057 1144816 and 1077979 are the the same patch, as documented in a comment for 1144816 by Oleg Broytmann. The wrong behaviour was reported to Mozilla (unspecified version), Netscape 7.2 and Mozilla-firefox (unspecified version). I could not reproduce the problem neither with Mozilla 1.7.2 nor with Firefox 1.0.1. Nevertheless, applying the patch does not break current functionality and might fix bugs in older browsers. I recommend applying 1077979, and closing 1144816.
