[Pkg-utopia-maintainers] Bug#714192: upower faiuls to detect devices => breaks battery monitor plasma applet

[valette]

Package: upower
Version: 0.9.20-2
Severity: critical
Justification: causes serious data loss

upower is currently broken on at least tree machines I have. ACPI info for battery is there, acpi -V works correctly
but upower fails with :

 upower --monitor-detail

(upower:7148): libupower-glib-WARNING **: Couldn't enumerate devices: Launch helper exited with unknown return code 127

(upower:7148): UPower-WARNING **: failed to enumerate: Launch helper exited with unknown return code 127

Conseqaunetly the battery monitor applet reports incorrect information on battery state and kde is unable 
to preventively shutdown properly the laptop => risk of data lost.
