Good, good. That part felt icky...

We the list of plugins (not the URL, I'm retrieving that from the job indeed) for the 
following case:

- a URL is dropped
- applets matching DropUrlPatterns are found
- the TransferJob returns an error

I Didn't make it up, this happens for the akonadi case if you don't have the KIO 
akonadi slave. 

My solution is to check first if we have DropUrlPattern matches and then only clean 
up without showing a menu if 

- no applets are there for this mimetype
- no DropUrlPattern matches

So in the mechanism, I think we really need it. The overhead should be negligible, 
since the memory is cleaned up after the popupmenu exits (note: forget that cleanup 
bit in the patch). 

Does it make sense now?

I think so, too.
