[Pkg-utopia-maintainers] Bug#1120712: upower: Journal swamped by upowerd "value "-nan" of type 'gdouble' is invalid...

[Debian Live user]

Package: upower
Version: 1.90.10-1
Severity: normal
X-Debbugs-Cc: ddbg72982+up at gmail.com

Dear Maintainer,

When I run recent versions of Debian, this is written to the 
Journal every 30s, as long as the system is up:

Nov 14 20:58:24 debian upowerd[1897]: value "-nan" of type 'gdouble' is invalid or out of range for property 'percentage' of type 'gdouble'
Nov 14 20:58:54 debian upowerd[1897]: value "-nan" of type 'gdouble' is invalid or out of range for property 'percentage' of type 'gdouble'
Nov 14 20:59:24 debian upowerd[1897]: value "-nan" of type 'gdouble' is invalid or out of range for property 'percentage' of type 'gdouble'

I suspect upower can't detect presence of battery.  This system
 ASUS X541NA doesn't have one.
I use this hardware for live system trials, and most wrongly show
"battery present" but some do get it right, eg, the
mate "Battery Charge Monitor" applet tooltip correctly shows:
System is running on AC power
No battery present

I'm used to systems that would log "message repeated 10000 times"
rather than actually logging the identical message every 30 seconds.
