It turns out that both PHP and Apache have limits on file uploads. The 
PHP limit was set to 2MiB, and there was also a PHP-specific Apache 
configuration that limited POSTs to 0.5MiB. So Apache responded to this 
upload with a 413 error. MediaWiki (perhaps wisely) does not add its own 
upload limit, though it does issue a warning confirmation for files 
bigger than 150KiB.

I've set both limits to 20MiB, and switched off MediaWiki's warning. 
I've uploaded Wouter's file to [[Image:TMR-Issue13.pdf]].
