500 Internal server error - register globals - export files

[thisdude]

Hi all

First of all, thanks to all developers who made this wonderful component. It has proven to be very useful!!

However, I'm experiencing some issues, and was wondering if someone could help;

When I generate exports (xml, xls, doesn't matter) formtools generates a 500 INTERNAL SERVER ERROR HTTP response code. (If the export group 'action' setting is configured 'open in a new window')
The user is not able to download the file, and firefox reports 'Firefox can't find the file at http://www.example.com/myformtools/modules/export_manager/export.php.'
However, if i inspect the payload, the content with submissions is actually in place.

I did some debugging and found out at what line it fails:
global/code/modules.php
around line 756
function ft_include_module($module_folder)
foreach ($GLOBALS as $key => $val) { @eval("global \$$key;"); }

this function is called in export_manager\export.php in one of the first statements
If i uncomment this line 756, everything works as expected, i get HTTP status 200 OK and the file can be downloaded.

I think I also know why: register globals is enabled
When register globals is disabled, there is no issue and the response code is also 200 OK

probably it tries to re-register already registered globals? ... am I clear here?

Could this be fixed by adding a check if-register-globals-enabled => do not execute the loop
else => execute the loop

Or should i report a bug for this?
