weird ascii null in output

Hi,

I encounter a funny thing here which I don't understand at all:

I have a template where, from some data passed in, I create output. Nothing uncommon so far. But, in ONE case ONLY (as far as I know now...) I get an ascii Null char in the resulting text.

This is the code snipped in question:

  {def $submitto=''}
  {if $data._submitto|is_string()}
    {set $submitto=$data._submitto}
  {/if}
  {def $form=concat('<form method="post" action=', $submitto|ezurl(), '>')}

$submitto is passed in as "/xxcontact/minireg"- that part works correctly.

Now, this is what I get:

wget -O - https://www.whatever.com/eng/xxcontact/minireg 2>/dev/null | grep -a 'action="/eng.*minireg' | hexdump -C
00000000  20 20 3c 66 6f 72 6d 20  6d 65 74 68 6f 64 3d 22  |  <form method="|
00000010  70 6f 73 74 22 20 61 63  74 69 6f 6e 3d 22 2f 65  |post" action="/e|
00000020  6e 67 2f <b>00</b> 62 73 63 6f  6e 74 61 63 74 2f 6d 69  |ng/.xxcontact/mi|
00000030  6e 69 72 65 67 22 3e 0a                           |nireg">.|
00000038

Notice the ascii Null before .xxcontact?

Now, I can leave out the ezurl() call, then I get the URL passed in, but again with ascii Null prepended.

So, my conclusion is that either the template framework or php itself is responsible. But - how do I fix this?

I use basically identical approaches for the creation of action urls in about 50 other places where I never observed this...

php is version 5.1.6, Zend engine is 2.1.0
eZ Publish is version 4.0.0 (yeah, I know there is a bug fix version available...)
