The plugin removes itself from the panel just after start (segfault?). I've configured to use hddtemp for /dev/sda in daemon mode. For an unknown reason, hddtemp doesn't start from /etc/rc.local automatically. All is fine after I started hddtemp manually.
plugin version is 1.2.5. xfce is 4.10.
Sorry, seems like I've posted previous commit about versions to wrong bug. My shame...
Thanks for reporting, fixed upstream.
