kioexec is only used when a program that can't handle remote URLs is being 
launched with a remote URL.

I really doubt this is the issue here, or something is very buggy. Are you 
100% sure that the code tries to run kioexec, with a local file? That should 
not happen.

Ah, maybe ksnapshot constructs a QUrl wrongly, from a local path and without a 
scheme, and then isLocalFile() return false. Debug the contents of the URLs 
being passed to KRun.

And why is kded5 not running? It's not installed?
