Crash

[georgkrause]

I updated signal-cli to 0.8.0 and siggo to 0.9.0 and have constant crashes:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference

I suppose this is related to group messages, but I can't say this for sure. I can provide more debug information if needed.

[georgkrause]

I try to run the latest master to verify if it might be solved already

No, as soon as a group messages is received, siggo crashes

[derricw]

Hey! Thanks for the report. I have not tested siggo with signal-cli 0.8.0 yet. I'll take a look at this as soon as I can.

[oto-ledger]

I've got the exact same issue, with signal-cli 0.8.1 and release 0.9 of siggo
