-Nahh, if you read some of the descriptions in the downstream Ubuntu bug
there are many devices that fail: the Ubuntu bug lists gps, headsets,
keyboards, modems, printer as failing, so currently it's more than a few
devices.
-A whole range of headsets seems to compute a fixed PIN based on their
serial number, so hardcoding wouldn't work at all.
-For some devices the random PIN seems generated on the device: "[my]
bluetooth headset generates a random PIN code each time it is put in
pairing mode (has an LCD display)"

This GPS device is a no-brand thing that is 2 years old and probably not
even sold anymore. Is it really worth adding special cases for such
niche products? I'd rather this were done in a way that helped all those
devices rather than just mine. (But yes, I'll file a bug on my device,
thanks :-))

Sorry, I understood your "Because if we don't force users to use random
PIN codes, they'll always enter
the same "easy" PIN codes." as 'don't ever allow people to enter
nonrandom codes'. But I am happy that this was a misunderstanding.

OK this is not feasible then. I'll happily admit I don't know a lot
about bluetooth, I just want it to get to work :-)

This would work just as well for me. I don't think the selection of
"0000" "1111" "1234" is needed, it makes the dialog quite wordy and
long. Why not just:
[X] Automatic PIN selection
[ ] Force a random PIN number
[ ] Use fixed PIN code: ___________
(many devices use 0000 or 1234)
I don't really get the difference between "automatic" and "force
random". I take it that automatic would include the special casing as is
done now, while random would only ever do random numbers?
I'd just go for:
[X] Random PIN
[ ] Use fixed PIN code: ___________ (prepopulate with 0000?)
and don't try to keep a list of special cases in code. Yes it does mean
that everyone needs to enter "0000" the first time the use their headset
but it makes things easy and transparent.
Will your solution work for above mentioned headsets that generate a PIN
on the headset and display it there?

I've never done anything GTK beyond following the GTK tutorials and my C
is quite rusty by now. If you want me to, I could try my luck, but I'd
rather if someone more proficient went for it first :-).
