-- Information about the crash:
The interface for Dolphin becomes unresponsive when trying to interface with an unresponsive WebDAV file server mounted with rclone, forcing me to kill Dolphin from the unresponsive window popup.

I have mounted a [copyparty](https://github.com/9001/copyparty) file server using rclone following the project's [documentation](https://github.com/9001/copyparty/blob/hovudstraum/docs/rclone.md#on-unix-clients). This works fine, including the mount automatically showing up in the "Remote" section on the left sidebar. However, if the copyparty server is terminated or the connection drops while a Dolphin window has the remote directory open, the entire Dolphin UI becomes unresponsive. I would expect Dolphin to show some kind of loading spinner or other placeholder, while allowing me to navigate somewhere else if the requested location can't be loaded, instead of becoming unresponsive and forcing me to close it.

I have briefly tested equivalent operations in the command line (e.g., trying to `ls` the copyparty directory while disconnected, interrupting the connection while `mv`'ing a file, etc.), and the behavior seems to be that `rclone` will indefinitely wait for the connection to return, blocking in the meantime. I guess this is fine for command-line applications, but it's a bummer when the UI of a GUI application freezes when a drive becomes unresponsive.

The crash can be reproduced every time.
