Please refer to the below link for more info:
The problem was reported by aTalk user while attempt to send an omemo message. aTalk displays an error message as shown below:
From the user debug log (see attach below) for tests on 1/12, below are my observations:
It seems that user clears all the omemo tables contents including the last active omemo device Id 1151002113 on 1/11.
Upon new launch of aTalk, omemo actually recreates a new OMEMO device ID 486745735; the new prekeys table was published onto the server and received a confirmation reply from server.
However what I observed is that when user try to send an omemo message, omemo seems to revert to use the old id 1151002113, hence the “null object reference” error; since there is no prekeys table for this device.
My expectation is that omemo should proceed to use the newly created id instead of the old deleted device id. Any explanation for this problem.
