I didn't notice this earlier, but I'd say they are *before* the
ServiceClassIDList:

[...]
Attribute Identifier : 0x0 - ServiceRecordHandle
  Integer : 0x10003
[...]
Attribute Identifier : 0x6 - LanguageBaseAttributeIDList
  Data Sequence
    Code ISO639 (Integer) : 0x656e
    Encoding (Integer) : 0x6a
    Base Offset (Integer) : 0x100
[...]
Attribute Identifier : 0x0 - ServiceRecordHandle
  Integer : 0x10003
Attribute Identifier : 0x1 - ServiceClassIDList
  Data Sequence
    Integer : 0x656e
    Integer : 0x6a
    Integer : 0x100
[...]

At least I've got a bit of a clue where to start looking now. :)

I'll need to fix up some things for that, I'll get back about this
later.  I tried debugging on the thing before, but there's some weird
problems with gdb on it.

Usually I try to get by with inserting printfs in various strategic
locations, but the problem here is that I'm not sure where to put
them...

Valgrind reports no problems, at least as far as I can interpret its
output.  (Attached as valgrind.dump.gz)

Hm, either my mail client or my mail server corrupted this specific
file.  I'm sending it again as a .gz file.
