The bug occurred yesterday under the following circumstances (non-reproducible, though):
N800-diablo.30-2
I did a usual session; logged on to home WLAN, started internet radio from home applet, ssh'ed to local gateway, VNC'ed on the local network, browsed a couple of external sites. Then I disconnected the WLAN using the statusbar icon (w/o stopping the radio streaming). An error message "connection to stream lost, reconnect?" popped up. I clicked on "reject" and then the current consumption went mad to at least 300 mA. I instantly ran htop only to get an indication of 10% CPU, 1 process running: htop itself. Locking the screen obviously didn't help. The supply current went back to normal when I forced "offline mode" in that state (although the status bar icon showed no active connection anyways).

Following scg, I'm posting a portion of my dmesg log. The second "shut down softmac" message is most probably the "forced offline" step. However, I don't fully understand how that "softmac" thing works. I hope that it is not anything similar to those horrible "soft modems" for windows?

/b.
