Comment 1 from the bug report linked -

While running xfce4 desktop - this xfce4-power-manager gets quite noticeable after a while in memory-eater hit-parade.

Wit just couple short uptime:
  509180 45752 24144 S 0,0 1,2 0:01.87 xfce4-power-man

now after few minutes:
  520096 48168 26168 S 0,0 1,2 0:01.95 xfce4-power-man

and growing continuously....

From plain --debug log:
