hello, 

i got an 500 internal server error everytime when something is not correct programmed. e.g. ValueError, missing input
This error only occured with internet explorer - but on older zope versions it works fine. 

Here it does not work: 
http://donau.kicms.de/koba/Error500Test (Zope 2.9.4-final, python 2.4.4, linux2)

Here it works fine in standard installtion: 
http://biomarkt.kicms.de/bio-markt/Error500Test (Zope 2.6.4 (source release, python 2.1, linux2), python 2.2.3, linux2)

IE Version: 6.0.2800.1106 SP1 - Windows 2000 SP4

the sourcecode of the Error500Test: 
<dtml-with newslettertool>
 <dtml-call user_add_sql>
</dtml-with>

It´s an easy call to an zsql method - and there are no variables defined. So the real error message which should be displayed: Missing input variable, u_title (Works with firefox) 

My Fix:
there is no change to do on standard_error_message. I have made an crazy change on the standard_html_header - the original standard_html_header is: 
---
<html>
  <head><title>&dtml-title_or_id;</title></head>
  <body bgcolor="#FFFFFF">
---

- This one does NOT work. Now i make it like this: 

---
<html>
  <head><title>&dtml-title_or_id;</title></head>
  <body bgcolor="#FFFFFF">

This one WORKS FINE - i dont understand why, but now i did not get any 500 internal server error on the internet explorer. I would be please if you can tell me why this crazy workaround works?

I now have set the workaround back to "not working" because of showing you the error.
