Comment 29 for bug 315996

Uninstalled inkscape, rebooted, reinstalled from Inkscape-0.47-3.exe downloaded from sourceforge Nov 26, put in the most recent launch_webbrowser.py. Ran inkscape help->inkscape manual. The first time that I did this no browser opened and the messages stopped just after the "before run". The second time it was run, again no browser window but the output included a traceback. The python release is still 2.5 not 2.51.
