--- Comment #1 from Olivier Tilloy <olivier.tilloy at canonical.com> ---
This bug was initially reported in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1589215.

According to the FreeDesktop Desktop Entry Specification¹, $XDG_CURRENT_DESKTOP
may contain a colon-separated list of strings.

The code in
https://github.com/LibreOffice/core/blob/master/vcl/unx/generic/desktopdetect/desktopdetector.cxx#L248
doesn't handle that well, as it tries to match (case-insensitive) on the whole
value of the variable.

This results in the desktop not being properly detected in instances where
XDG_CURRENT_DESKTOP = "ubuntu:GNOME" (which is the case in Ubuntu 18.04).
