Hello,

I am using apturl-kde successfull with firefox.
It works with konqueror KHTML, but when I switch to Webkit render engine, I experience this:

Clicking on an apt-link (for example: apt://skype) brings up a page with the following error message:

"Unable to create io-slave: klauncher said: Error loading 'apturl %u'"

Now typing the Link-URL (apt://skype) directly into the location bar of Konqueror and hitting "enter" will invoke bringing up AptURL dialog asking to install the software!

So how can I make Konqueror handle clicking on the apt://package-url correctly?

This appears to be a bug from what I can tell - in the code supporting the Webkit rendering engine, in this case probably the Webkit KPart.

I would suggest filing a bug report at bugs.kde.org regarding this, as only adjusting the code will fix this.

Any other way to make a temporary fix?
Since webkit with rekonq does work correctly?

Maybe it's got to do with the '%u' parameter that is defined in the apt.protocol and apt+http.protocol under usr/share/kde4/services?

The %u ensures that it does work - that instructs KDE where to place the url you clicked. Rekonq uses it's own, different implementation of the Webkit supporting code - hence why it is not affected.
