can't share

After many years of absence, I am trying to get back into soulseek using Nicotine+.

Installed it through Flatpak on a debian based system. Application seems to work fine... except: clicking the "Add" button on the Shares pane of the settings menu does nothing. No dialog opens, no error message is shown, just nothing. Is it a known bug with an easy fix?

EDIT / SOLVED: appearantly when one logs into a remote desktop session, the file picker sometimes crashes. For anyone encountering same issues: login directly instead of remotely, or use suggested solve: https://discussion.fedoraproject.org/t/file-chooser-does-not-open-for-flatpak-applications-f40-sway/126351/4
