Kodi 18 - 'cannot save setting' for backup location on usb

[Nachteule]

@jakenl, Update:

Testing with an exFAT partition, and I'm getting same issue. It depends on exFAT but exFAT is not the culprit. The problem is that XBian-config GUI sends wrong filename, no idea why, nothing changed for years [1]

Will have to investigate what's going on, being quite confused

[1] Filename for example is /media/exFAT/$\(hostname\)_xbian_image_$\(date\ +%F\).img for example, '(' and ' ' character is escaped and this is the problem
