Mount point it is probably a symbolic link
Hi, while trying to make a Snap for GWE I bumped in this issue:
main.go:224: cannot change mount namespace of snap "gwe" according to change mount (/snap/gtk-common-themes/818/share/icons/Suru /snap/gwe/x1/data-dir/icons/Suru none bind,ro 0 0): cannot use "/snap/gtk-common-themes/818/share/icons/Suru" as bind-mount source: not a directory
It can be reproduced checking out this commit.
A user on the snapcraft forum suggested to open an issue here.
Let me know if I can help in any other way.
