No idea if that's the problem but one known issue with external
interaction to hlr.sqlite3 is that the binary coding/decoding routinge
(to store binary data inside sqlite) are not standard.

The DBI interface we use has it's own routines and if you try a
'native' sqlite3 driver, you may not get the right data. When
accessing binary data fields from a auto-provisionning app for 27c3
from a python script, I actually had to write my own 'dbi-equivalent'
binary coding routine ...

See the dbi source code for more info about the algorithm itself.

Cheers,
