miro player with firefox browsing flash at the same time causes system crash

Binary package hint: miro

When I play a video in Miro player and at the same time browsing web pages with embedded Flash in Firefox, it causes system crash. I reproduced this bug more than 10-times.

How to reproduce:
1. open miro player, play some video
2. open firefox, browse some flash-powered web pages
3. wait 3-5 seconds

Then the video in Miro stops. Sound continues. After 1-2 seconds the whole screen is distorted, strange colored lines appear. The whole system is frozen.

I use freshly installed Ubuntu 11.04 with default Firefox and Miro packages.
