Xdg-user-dirs does not support Wayland. This results in no XDG User Directories being created on (first) login. The current script uses Xsession.d that does not work under Wayland. Some distributions (Fedora) added autostart .desktop files to do the job under Wayland, but they did not upstream this.

patch from Debian
This patch was recently applied to Debian and Ubuntu.
Ah, I wasn't aware of this bug report... I've sent a slightly older version of this patch to Alex in an email (to have any chance of it being applied upstream).
Obviously this bug report is the better place to track this issue, and I hope someone will notice it.... ;-)
Added this and released 0.16:
Great, thank you very much!
