    How about a setExec() method rather than a special constructor? This seems a lot clearer to me (and e.g. easier to grep for in order to find usages, etc.).
    
    
    But anyway, I have my doubts that this really works: returning a KService that isn't exactly like the one in ksycoca seems fragile to me.
    E.g. when krun uses that service, it will call KToolInvocation with the entry path to the service - i.e. just the path to the desktop file. The modified Exec field (in memory) won't be used in that case.
    
    What KRun can do, though, is work with a "temp" kservice, created like this:
    
        KService::Ptr service(new KService(_name, _exec, _icon));
    
    This is detected as "not in ksycoca" and therefore not given to KToolInvocation (but to runTempService).
    
    I think this would recreate the issue you saw though, since indeed nowadays it's not enough to have %U in the exec line, one must also have Categories or X-KDE-Protocols indicating that KIO protocols are supported. But this could be copied from the orig file, using a new setter in KService. Hmm.
    
    Maybe it would be simpler to just clear entryPath() in the KService::setExec() I'm suggesting initially. i.e.: if we're modifying the KService then the path to the file that has been cached in ksycoca, no longer applies.
    And then KRun will go to runTempService, when running it.

    this comment should move with the code that it affected

That is a local copy of the file is created first. Currently this problem can be reproduced with kate because the "Exec=" line in its desktop file contains an additional option, "-b".
