Files don't open with double click but inside libreoffice they did

When I try to open libreoffice files double clicking on them, libreoffice start loading, the splashscreen appear then the loading stop here sometimes lefting a temporary lock file in the same directory of the file I try to open; but if I load the application (eg. writer ) and use the open command from the menù or the icons the file is loaded normally.
I’ve tried to resolve this annoying problem updating to 3.6.4 but nohing changed.
Someone can help me?
