Hi,

I upgraded to Ubuntu Karmic and found problems when using the command sdptool.
I was found that the problem only when use the kernel 2.6.31,
using the old 2.6.28 Kernel sdptool the command works correctly.

Note: We also did the test by downloading the Vanilla kernel
kernel.org site and the same error was found.

The commands sequence above reproduce the scenario:
