Memory leak in xfce4-netload-plugin and xfce4-systemload-plugin - only on FreeBSD?

[Torfinn Ingolfsen]

Update: I have now updated to Xfce 4.10 and the problem still persists.
Data point: I have a laptop which runs Xubuntu 12.04 (which uses Xfce
4.8). I run the same xfce plugins there, but do not see any memory
leak in them.
Any hints on how to better narrowing this down, or how to fix it are welcome.
