[Bug 420256] [NEW] Bluetooth applet doesn't detect any devices

[Krzysztof Kosiński]

Public bug reported:

Binary package hint: gnome-bluetooth

On a system upgraded to Karmic, the new Bluetooth applet doesn't detect
any devices; the spinner just keeps working indefinitely and nothing
appears. On the other hand 'hcitool scan' works correctly and detects
all devices. The D-Bus interface, when used from Python, works correctly
as well. I suspect it is a bug in the applet.
