It'll do that if you click your plugin toolbar icon while a device is connected, then disconnect, and then close the dialog. Happened to me and Kovid said it was losing context somewhere and would need looking at. Never did open a ticket as I worked around it by only showing an icon when device is connected.
P.S. Would have been a longer replied, but 11.04 crashed - again - and I lost it...
