```

```

This happens on exactly one (that I have found) of my conversations and on
exactly the same message every time.

On further inspection, this assert is failing because a message which should
*not* already exist in the cache (because of some feature of the message) has
been re-created.

On further inspection, the PDU which is failing has type
"PduHeaders.MESSAGE_TYPE_SEND_REQ", so it hits this branch:
https://github.com/klinker41/android-smsmms/blob/f6fa7d379444dc11d700fe6178b418bd76cfb88f/library/src/main/java/com/google/android/mms/pdu_alt/PduPersister.java#L637

I do not know why this message is any different than any other. I suspect some
corruption of my MMS database.

STEPS TO REPRODUCE
1. Wave magic wand to cause MMS message with PDU msgType ==
MESSAGE_TYPE_SEND_REQ
2. Attempt to load this message with the KDE Connect SMS app (or similar)

OBSERVED RESULT

KDE Connect Android app crashes. The KDE Connect SMS app never updates

EXPECTED RESULT

KDE Connect Android app should not crash, the SMS app should update.

SOFTWARE/OS VERSIONS
Android 10
OnePlus 6T
