unicode error with win32 builds

[Antoine Martin]

With 2.4.?

Stacktrace reported as a picture (..):

xpra/scripts/main.py line 68 in main
xpra/scripts/config.py line 1178 in make_defaults_struct
xpra/scripts/config.py line 389 in read_xpra_defaults
xpra/os_util.py line 486 in osexpand
xpra/os_util.py line 451 in shellsub

My guess, based on the screenshot is that this is a character encoding issue with the username or home path.
