[snap] libreoffice fileselectors does not show thumb drives

[Roland Hughes]

Because of the move to a snap, when one opens the file dialog usb/thumb drives are not shown. For a File->Open you can navigate to /media/user-name/thumb-drive if and only if you personally have mounted the thumb. For those of us writing documentation using screen shots taken on many different systems but all on the same thumb drive this is a real hassle.

Prior to Snap packaging this worked.

I suspect this is a nasty bug in Snap.

Thank you for your bug report. The fileselector is a GTK widget and not nautilus and it's an issue with the snap. It uses the removable-media interface but that doesn't seem enough to get access to removable keys for some reason?

The journal log has denials access to /proc/<pid>/mountinfo , the mount-observer interface would resolve that but unsure if that's the issue or a redherring

The issue would be fixed if the snap was using portals but as described in bug #1881603 that's not trivial since it would require using newer GTK API calls
