To reproduce the bug (fedora 30)
1) Create a sshfs on a remote machine from your home directory (sshfs user@machine:/home/dir ~/SSHFS)
2) Lock the screen (I use gnome)
3) Unplug the internet cable fo your machine for example 
4) Wait a minute and replug the cable
5) Try to log back in your gnome session.
After I enter the password, the time wheel froze and nothing happen anymore
You can log on the machine through a stty, and kill the gnome-session to have a new graphic session.
After that it may happen that you cannot make the same sshfs again without restarting the machine.

Sorry, there is a mistake in my previous message:

Here is the new procedure
1) Create a sshfs on a remote machine from the home directory (sshfs user@machine:/home/dir ~/SSHFS)
2) Lock the screen (under gnome)
3) Unplug the internet cable of your machine for example (or stall the internet connection, by another way)
4) Try to login back into the gnome session.
After entering the password, the time wheel froze and nothing happens any more
login on the machine is possible through a terminal tty, but a ls command must also fail (because of ~/SSHFS)
Reconnect the internet cable can re-establish the connection nad let login normally.
But, if the connection cannot be unstalled, there is not way to login properly, unmounting the sshfs properly seems impossible.
It may require to kill the gnome-session, or worst to restart the machine.
