Rubberband-bug when executing files.

Dear maintainer,

the latest version of libfm has the very annoying bug that if I click some executable file and pcmanfm asks how and if it should be executed it also starts drawing the rubberband (which is then visible after I close the dialog and can't be stopped until I click again onto the icon view.

After digging through the code I found that by removing the lines in the commit solves the problem, however the comment suggests its already a bugfix for something else.

Best regards
Gregor Bollerhey
