[Xavi]

I have two usb wireless devices plugged in
(1) SVEON SNT 1020, which uses the chip Ralink 3072 (RT2870). This device is not properly configured with Ubuntu 11.04, regardless of the installed packages found in ubuntu repos (it was supported like "plug and play" still in 10.04 LTS, with the ralink packages).

(2) A USB Zydas ZD1211B, which works out of the box /(plug and play).

I also had the ethernet cable plugged in.

After working with no problem for 1h+, and while writing a long email with thunderbird, I saw this popup saying that a bug was found, and a report was to be sent to launchapd.
And here it is.
