This is probably the netlog code putting binary data in strings.

That's a valid hypothesis.  Could have been something like what was fixed at https://crrev.com/c/570627.  (This was unsanitized binary data received over the wire.)

This particular repro is logging headers from a PUSH_PROMISE, which contain non-UTF8 characters.

That logging comes from here:

ClusterFuzz testcase 5741102614446080 appears to be flaky, updating reproducibility label.

Please ignore the last comment about testcase being unreproducible. The testcase is still reproducible. This happened due to a code refactoring on ClusterFuzz side, and the underlying root cause is now fixed. Resetting the label back to Reproducible. Sorry about the inconvenience caused from these incorrect notifications.

Change SpdyHeaderBlockNetLogCallback() dict value type.

SpdyHeaderBlockNetLogCallback() returns a base::DictionaryValue with a
single entry with key "headers".  This CL changes the value of that
entry from a base::DictionaryValue to a base::ListValue.  The motivation
is that this way duplicate code with ElideSpdyHeaderBlockForNetLog() can
be eliminated, so it will be enough to fix  https://crbug.com/800282  in
one function.

Also make sure that unittests only use base::Value methods that are not
marked as deprecated.
