Comment 18 for bug 563207

Hi Jeremie,
  I get a similar but different error if I run that app in my environment:

python: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.
python: ../../src/xcb_io.c:140: dequeue_pending_request: Assertion `req == dpy->xcb->pending_requests' failed.
Aborted (core dumped)

For those trying to reproduce it, I took Jermeie's program and had to

apt-get install python-wxgtk2.8 python-matplotlib python-pyaudio

I run it, ok the error about the missing icon, and hit the start button, I get the following output:

ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear

I got the interesting error (the one at the end) 3 times out of 4 tries.

This is on Oneiric on an i7-860 running KDE desktop. It's possible it's the same problem given it's a similar error - and the fact his test is so reproducable seems a good start.
