iPlayer on 64-bit ubuntu

When visiting www.bbc.co.uk from a 64-bit ubuntu 9.04 (jaunty) laptop, the following odd symptoms were observed:

Very obscurely, the solution wasn't to reinstall iPlayer nor Adobe AIR, but

sudo aptitude install lib32nss-mdns
Sometimes the various attempts at getting iPlayer working leave a broken encrypted local storage directory behind leading to hangs and/or interesting files in /tmp/airCrashLogs. A new hopefully working directory is recreated after
rm -rf ~/.appdata/Adobe/AIR/ELS
