Bizarre bug with inline error messages

Guys,

This one is rather confusing, and worrying me. I will be rifling  
through the WM source shortly to see what I can find but thought I'd  
raise it here first in case somebody has already been down this path.

Basically, in -some- cases, but consistently, we are getting a  
garbled inline HTML comment error message coming out when evaluating  
a null. What is worrying about this is the nature of the garbling...  
see the output HTML:


<h1>Game Referrals</h1>

<table>
<tr>
     <td>Total game referrals last month</td>
     <td>6</td>
</tr>

<tr><td valign="top">By game</td>
<td>
<table>
<tr>
     <td>[<!-- Value is null: $Form.gameID at /var/www/ignition/ 
module]:</td>
     <td align="right">1</td>
</tr>
<tr>
     <td>[BIKE]:</td>
     <td align="right">1</td>
</tr>
</table>
</td></tr>

OK first problem, the "-->" is missing from the end of the comment.  
Then you realise that "/var/www/ignition/module" is not the full path  
to the template that caused the problem. So we have some error output  
truncation going on.

Then you realise that $Form.gameID is not even the variable it was  
evaluating?! The template fragment that generates the above is here:

<h1>Game Referrals</h1>

<table>
<tr>
     <td>Total game referrals last month</td>
     <td>$model.statsGameReferrals.c</td>
</tr>

<tr><td valign="top">By game</td>
<td>
<table>
#foreach $row in $model.statsGameReferralsByGame
<tr>
     <td>[$row.v]:</td>
     <td align="right">$row.c</td>
</tr>
#end
</table>
</td></tr>

...so any ideas why it is getting completely the wrong variable  
reference in the error here? $Form.gameID is not referenced anywhere  
in this template, nor any of its includes.

This is worrying because it feels like a thread safety problem.

Thanks in advance,
Marc
