No, ~username at the front of a path is supposed to be expanded to the home 
directory of username.  I just read about this yesterday in some unix 
programming faq. The correct(untested) code is.

#include <pwd.h>
#include <sys/types.h>

static void fixHomeDir(QString &dir)
{
	if (dir[0] == '~')
	{
		if( dir[1] == '/')
		{
			dir = QDir::homeDirPath() + dir.mid(1);
			return;
		}
		struct passwd * ps = getpwnam( dir.section('/',0,0).mid(1).latin1() );
		if( !ps )
			return;
		QString home(ps->pw_dir);
		if( home.size()==0 || home[home.size()-1]!='/' )
			home+='/';
		dir = home + dir.section( '/',1 );
	}
}
