trouble with html form after Debian upgrade to Bookworm

Hi all,

I host a few case/customer management applications developped with mod_perl on Debian; these applications provide html forms with which users can record documents pertaining to the case/customer. 

These forms include various <input type=text|hidden|file> controls. A user may update a record to change the document or some text field, like the date, without changing the document itself (see the signature for an example, select any file in the demo account, click on the 'Documents' tab).

After I upgraded my servers to Debian Bookworm, my users signaled that they could not simply update a text field anymore : a document was to be selected, otherwise no change could take place. It appears that the <input> fields on the form placed AFTER <input type=file> did not find their way into @args if the latter was empty.

Correcting the problem was simple : in my html page, I simply placed the <input type=file> control last, and all controls are now submitted even when no new file is present.

I'm wondering if any of you has an idea of what caused this change in behaviour?
