When I try to open a file '/home/francisco.campos/H:/Coordinacion/Programa de trabajo 2010/programa 2010.planner' appears an error message and the file is not loaded, althought if I rename the directory H: as H, I don't have any problem, but I think is not the correct solution, because PLANNER is the only application that causes this error.

mrp-project.c

/* Get a local file from the uri. */
	if (len > 3 && !strstr (uri, ":/")) {
		/* No protocol. */
	} else {
		if (len > 7 && !strncmp (uri, "file:/", 6)) {
			/* Naively strip method. */
			uri = uri + 7;
		} else {
			g_set_error (error, 
				     MRP_ERROR,
				     MRP_ERROR_INVALID_URI,
				     _("Invalid URI: '%s'"),
				     uri);
			
			return FALSE;
		}
