Sorry, I was on a short holiday.
I always use the protocol - it's one of the things I had to tweak about opera. But as I said: it is known that Chromium blocks ports. Here's the list, straight from the source code (and with line numbers):
namespace {
// The general list of blocked ports. Will be blocked unless a specific
// protocol overrides it. (Ex: ftp can use ports 20 and 21)
static const int kRestrictedPorts[] = {
1, // tcpmux
7, // echo
9, // discard
11, // systat
13, // daytime
15, // netstat
17, // qotd
19, // chargen
20, // ftp data
21, // ftp access
22, // ssh
23, // telnet
25, // smtp
37, // time
42, // name
43, // nicname

My astonishment is both at the fact that no one seems to care about this - if IE would do this, it'd be a a front-page scandal on every tech site - and at the apparent lack of solution either.
From what I found on the internet, there used to be a setting called 'permitted ports'in earlier builds', but it seems to have disappeared. Apparently I'll have to get the source somewhere (if possible), edit - rather: clear- the list and compile my own version. Which obviously isn't very user-friendly.
