<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I would add a NoError = 0 at the beginning of the enum, since in case no error occurred we need a value notifying that.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not so sure. I used kservice and kpluginloader as models for the error handling. One has an error() method and one passes the error in the arguments, but in both the error string could be stale if no error occured. Since callers shouldn't be checking the error code/string unless the returned pointer is null, I don't see any point in providing a NoError code.
Maybe I should document this in the header file?</pre>

Attempting to load a configured action on a machine where it is not
supported (e.g. DPMS when the display doesn't support it or it is not
compiled in) fails and brings up a notification, something that is
particularly intrusive during login.
Provide a method for ActionPool::loadAction callers to ask why the load
failed. PowerDevil::Core::loadProfile uses this check to decide whether
to warn to stderr rather than notifying the user of a misconfiguration.
Other loadAction callers are unchanged.
Action loading failure may be due to an error during initialisation or
simply because no such action exits. In the former case the error must
be recorded so that it is available to pass on to later loadAction
callers.
NB: A more complete fix might involve detecting whether the action is
supportable when loading the action configuration and/or in the profile
generator. However that may not turn out to be a feasible approach.
