This updated patch should correct the things pointed out by Chris and MPT:
1/ The basename is used rather than the full path
2/ Quotes are changed from "'" to "\""
3/ Added a period to the end of the sentence
4/ Set the default response to GTK_RESPONSE_OK
5/ Hides the status icon when the dialog responds (thanks to Nicolò for spotting this!)
