Bug#973549: wine-development: 000d:err:menubuilder:init_xdg error looking up the desktop directory
Ok, I found a very easy way to reproduce this «bug» error message.
Run a first (without ~/.wine) wine having in .config/user-dirs.dirs something
Then delete (rm -rf) this $HOME/Desktop and update .config/user-dirs.dirs to :
and then run wine again.
Conclusion: wine is keeping the first value in ~/.wine and does not update it on
the next run for probably some (good?) reason.
