I don't think it makes sense to deviate here in this one method, if that's desirable it should be changed everywhere in a separate commit IMHO.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In case you mean that the check should be done using isEnabled() right at the start of the method (i.e. before the if):
I'm not sure this check is needed at all in the ksecretservice case, there is no ->getInterface().xxx call that could crash.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">KWalletDLauncher does check whether the wallet is enabled and just returns if not without doing anything. This means it doesn't start the KWallet service in the non-ksecretservice, that's what causes the mentioned crash in the first place because a nullptr is dereferenced.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I don't know anything about ksecretservice, but the code here probably will return false in case the wallet is disabled anyway (at least that's my feeling after looking at this code).</p></pre>

This affects e.g. drkonqi, but probably also other applications.</p>
