Page customization ends with HTTP 500 on APEX 4.0, 3.2 & 3.0

Question

Hello,
I'm very pleased how well APEX Listener works with our existing applications (100s of pages). So far we've found only one issue we can't work around:
The problem occurs when user is trying to save page customization when using APEX Listener.
Steps to replicate:
1) Create an APEX page with region and set "Customization" to "Customizable and Shown By Default"
2) Run the page & click on "Customize" link
3) The customization pop-up is presented
4) Click on "Apply changes"
5) Error: HTTP Status 500 - System Unavailable. Please try again later.
The Apache Tomcat stdout log is attached bellow.
When we use Oracle HTTP server (running on the same database) no error occurs.
Configurations (3 environments with the same results):
* APEX Listener 0.10.110.10.57
* Apache Tomcat 6.0.26 (Windows)
* APEX 3.0.1 & Database 11g Release 1 (Windows)
* APEX 3.2.1 & Database 11g Release 2 (Linux & Windows)
* APEX 4.0.0 & Database 11g Release 2 (Windows)
Thanks for any ideas,
Jan

I am having similar error when I just click on a different tab.
My environment is:

Oracle 11g 11.0.0.7 64 bit
APEX 4.0
APEX Listener version :0.10.110.10.57
Tomcat 6.0.26 64 bit
