Comment (by ttcoder):
Just had a similar KDL (occurs very rarely here), starting from
BSecureSocket::WaitForData() instead of BSecureSocket::Disconnect() if I
recall.
I say "if I recall" because I don't have the full backtrace: I expected it
would be in `previous_syslog` but unfortunately the interesting part is
corrupted/truncated by some trailing 'color codes' themselves followed by
seemingly random binary garbage:
