Bug description

I understand that Virtual File support on Linux is experimental at this time, but figured I would report this in case anyone else has encountered this before. I have the Nextcloud client installed on my (Manjaro) system and doing Virtual File syncing to just the default Nextcloud folder in my home directory. When I select .nextcloud files from within there, the file is properly fetched and displayed as I would expect. However, I have some bind mounts set up from my Nextcloud folder to other locations in my home directory, and when attempting to open .nextcloud files from those locations, the fetch and display action doesn't seem to work. It appears to start to work since I see the Nextcloud app pop up briefly, but nothing happens after that. The bind mounts I have look like:

/home/user/Nextcloud/Documents  /home/user/Documents    none    defaults,bind   0 0

Steps to reproduce

1. Set up Nextcloud account with Virtual File support on client
2. Bind mount directory within Nextcloud folder to another location
3. Navigate to bind mount directory
4. Double-click (or otherwise attempt to open) any .nextcloud file within

Expected behavior

Double-clicking the file would have the Nextcloud client fetch and display the file normally.

Hi @Ziris85 - Thanks for the report. I know this was a awhile ago. Are you still able to reproduce this behavior? And if so, does anything appear of interest in the client-side debug logs?
