filestore node update issue

I have filestore set up and almost working on 4.3, with a taxonomy set up for the files.

When I upload a file, it all works properly. I display them via "/taxonomy/page/or/10" (10 being the term id that I have assigned to the uploaded files). This all works fine.

If I then click the administer link for one of the files and immediately submit (changing nothing) and go back to the "/taxonomy/page/or/10" link, the HTML returned by drupal is truncated halfway through (just after my left blocks, but before the content area starts). I get no main content, no right blocks and no footer. Even worse than that, I get no error logs anywhere. Not in watchdog, not in the mysql logs, and not in the apache error logs.

To back out of this situation, I have to manually remove (with phpMyAdmin) the entries from the node table, the filestore table and the fstore_upload table, as trying to delete them from manage content resulted in the same problem with the confirmation page: HTML truncated after left blocks and no error logs to point me in the right direction.

I also noted that there were a couple bare fstore_upload tables in the SQL queries in the module code. I have added the curly braces in my copy of the module. (I had to as I am using a db_prefix).

I am running this on RedHat 7.2 with Apache 1.3.29 and PHP 4.3.4
