BUG+FIX - panic in octstr.c

Function is convert() in  gwlib/octstr.c

Offending code is;

...
    case 'E':
        new = octstr_duplicate(va_arg(VALST(args), Octstr *));
        if (!new)
            new = octstr_imm("(null)");
	octstr_url_encode(new);
...

You can't pass an immutable Octstr instance to the octstr_url_encode()
function.

Change the octstr_imm() to octstr_create().
