Description Stefan Brüns 2010-03-14 18:06:36 UTC 
Version:            (using KDE 4.4.1)
Installed from:    openSUSE RPMs

The timer is fired also when:
- dataengine is not queried at all
- hddtemp is not available

Proposed solution

Data queried from hddtemp is cached. After the mainloop finishes (and all clients of the dataengine with the same interval are done), the cache is marked as invalid by the timer.
If the connection to hddtemp fails, the timer is not restarted
If the dataengine is not queried at all, the cache is marked as invalid once, but the timer is not restarted.
