gvfsd hangs on hanging filesystem

[Julian Andres Klode]

This means that no file open dialog works anymore. I needed to restart gvfs-daemon.service twice today in order to attach two files in chrome.

There seems to be some issue with samba, but not sure what it's trying to connect to or why it hangs the entire thing.

It is also impossible to start nautilus. It hangs polling its eventfd. Running in strace it eventually continues to then crash in libfontconfig (might be some memory limit by my strace wrapper, though).

I now do not see the error messages, but still have to restart gvfs-daemon before I can attach files / desktop portals open

Seems this ws all down due to a hanging /keybase FUSE file system, so not as critical a bug as I feared (basically nautilus and desktop portals become unusable when a filesystem hangs).

Thanks for the details, indeed it seems a special situation and not a rls blocker
