--- Comment #4 from Kai Uwe Broulik <k...@privat.broulik.de> ---
Git commit be3b80e78017cc6668f9227529ad429150c27faa by Kai Uwe Broulik, on
behalf of Oleg Solovyov.
Committed on 19/10/2018 at 13:29.
Pushed by broulik into branch 'Plasma/5.12'.

Plasmashell freezes when trying to get free space info from mounted remote
filesystem after losing connection to it

Summary:
Related: bug 397537

Earlier plasmashell assumed that you'll get free space info immediately (which
is not true in case of losing connection to server containing a mounted
filesystem - statfs will wait for response forever and freeze everything since
it's happening in main thread)

I moved obtaining that info into different thread so that case won't freeze
anything anymore.
It creates exactly one thread per one path. If a path is already being
processed, new thread won't be created.
Also I implemented a timer used to notify about broken connection after 15
seconds.
