Happend twice now with the same backtrace.

[egbertbouman]

Already fixed in latest IPv8, we just need to update the pointer.

Updated Triber/pyipv8 to master, now the error is not happening.

But Token Balance stays -. If I click on it, I receive An error occurred during the request: the user with the provided public key could not be found.

[qstokkink]

Tribler is not compatible with the latest IPv8 pointer. The get_latest_blocks() changed its function signature and #4503 will have to be merged (or the market removed).
