Description of problem:
Some Flash video streams don't work with Adobe's Flash plugin wrapped on a x86_64 system, but work wrapped on a i686 system. The Flash player doesn't crash. It just doesn't play the video.
An example: http://www.tagesschau.de/multimedia/sendung/ts4932.html
I tried to capture the network traffic with Wireshark. Please take a look at the attachments. After the Flash player is loaded on the i686 system, it sends a DNS request for the streaming server. This isn't the case on the x86_64 system. Something seems to prevent the flash plugin from doing some network activities. I suspect nspluginwrapper. But I don't know how to debug further.
Things like YouTube work without a problem.

Steps to Reproduce:
1. Go to the mentioned URL
2. Start the video
3. Look what (not) happens
On a x86_64 the video doesn't play, but it does on a i686 system.
The video should play on a x86_64 system too!

This can be fixed by installing the package nss-mdns.i386
I guess this dependency should be in flash-plugin.i386. So there is not much we
Another note: this only happens if nss-mdns.x86_64 is installed. It's not clear
to me which component is to blame. It could be everything from flash-plugin to
glibc/nscd. Perhaps it could even be considered as NOTABUG.
