We had something of a discussion about this - it's usually not just
BSSIDs/MAC addresses, but also encryption keys (say WEP keys, or at
least temporal keys, sometimes more), SSIDs, etc. In short, there's a
whole bunch of private data that can be included in such dumps.

However, we haven't really found a good solution. Popping up big scary
warnings to the user is unlikely to be productive, trying to keep the
data private and only accessible to (the right) developers is not going
to work ... encryption might work, but who manages that?

Certainly the data shouldn't be attached to a public bug tracker
