Arch Linux

Description:

Starting solfege fails with this Python exception:

Traceback (most recent call last):
File "/usr/bin/solfege", line 58, in <module>
import solfege.startup
File "/usr/share/solfege/solfege/startup.py", line 45, in <module>
from solfege.mainwin import MainWin, SplashWin
File "/usr/share/solfege/solfege/mainwin.py", line 28, in <module>
i = webbrowser._tryorder.index("x-www-browser")
AttributeError: 'NoneType' object has no attribute 'index'

Additional info:

Repositorium : community
Name : solfege
Version : 3.23.4-1

I would file a bug report upstream here https://savannah.gnu.org/bugs/?group=solfege, but it would require me to open another account, which I don't want and upstream doesn't seem to fix bugs in a timely manner anyway and the fix can easily applied during package building (see below).

Steps to reproduce:

Start 'solfege' from a terminal command line.

Analysis:

The 'mainwin.py' Python file tries to access the (non-public) module global '_tryorder' from the 'webbrowser' module as a list, before it is initialized by the 'register_standard_browsers' function, but then it is still 'None' and this has no 'index' attribute.

Suggested fix:

Insert the following line before line 28:

webbrowser.register_standard_browsers()
