I'm not sure if this is a client or server issue, but with raven-python 6.1.0 I've noticed that lately we encounter instances where a dictionary will render incorrectly in the UI, which makes debugging much harder.
For example:

for a Python dictionary that is roughly:
{'filter': {'bool': {'must': [{'term': {'page_type': 'post'}},
{'term': {'apikey': 'someapikey'}}],
'must_not': [{'term': {'recrawlable': False}]}
馃槀 looks fine to me. (thanks for the issue dan, I think i've noticed this too.)
@dan-blanchard I stumbled across a similar problem as well just now, and I think #6636 should fix it for your case too.
@alex-hofsteede so happy to see a fix is coming soon!
This is merged. It won't go back and fix any past events that were serialized this way, but should prevent new data from having this problem.
