That would actually make sense. That message was logged with that
format in MM 1.10.x, but not in MM 1.12.x:

aleksander at poseidon:~/Development/foss/ModemManager:(mm-1-12)$ grep -r
"Found PDP" .
aleksander at poseidon:~/Development/foss/ModemManager:(mm-1-12)$ git
checkout mm-1-10
Switched to branch 'mm-1-10'
Your branch is up to date with 'origin/mm-1-10'.
aleksander at poseidon:~/Development/foss/ModemManager:(mm-1-10)$ grep -r
"Found PDP" .
./src/mm-broadband-bearer.c:                mm_dbg ("Found PDP context
with CID %u and PDP type %s for APN '%s'",
./src/mm-broadband-bearer.c:                mm_dbg ("Found PDP context
with CID %u and no APN",

Could it be that the log is really from a MM 1.10 run instead of a MM
1.12 run? The fix to ignore disconnection reports when PPP is used was
only added in MM 1.12.0 IIRC.
