I tried changing use_gio_unsafe_file_saving to off and it worked.
Then I set it back to on, and it still works. Opening files from sftp mounts directly inside geany works, and also in nautilus Open With geany works. I can no longer reproduce the problem; it's weird because my desktop workstation was not rebooted since yesterday when I opened this
So I guess I should close this issue for now, or wait a bit and see if I manage to find the way to reproduce the problem.
