Title:
Enable bubblewra
Yep: @nicolas-bernaerts is right. Ubuntu should include this commit:
https://gitlab.gnome.org/GNOME/gnome-
desktop/commit/259e7e4edb0d9b84fb7cf0847149ff8d42ab9a56
since we have unmerged /usr.

https://gitlab.gnome.org/GNOME/gnome-desktop/issue
I've also encountered the same trouble with some of my external
thumbnailers (lo-thumbnailer, msoffice-thumbnailer, ...).
I realised that bwarp calls fail under Ubuntu and Debian because of

Well, from reading gnome-desktop-thumbnail-script.c I understand
thumbnailer does not have access to /usr/local, so changed
raw.thumbnailer content to:
[Thumbnailer Entry]
Exec=/usr/bin/ufraw-batch --embedded-image --out-type=png --size=%s %u
--overwrite --silent --output=%o
MimeType=image/x-cano
This change just landed in bionic, and now my raw.thumbnailer does not
work anymore. :(
raw.thumbnailer content:
[Thumbnailer Entry]
Exec=/usr/local/bin/raw-thumbnailer.sh %s %u %o
MimeType=image/x-canon-cr2;image/x-cr2;

Don't we need the changes to bubblewrap itself too?
