Bug report today from a WP.com user (internal ref 814545-f) saying that the desktop app started crashing shortly after they installed it on a new Linux installation - Ubuntu 16.04 LTS. Re-installing the app makes no difference.

They then tried Calypso in Firefox where they receive this same error, Reducers may not dispatch action. They also receive unresponsive script errors in Firefox:

User claims they're unable to open the console before Firefox freezes and needs to be restarted. The problem also occurs in safe mode in Firefox. Chrome works without any errors, as do other devices on the same home network.

Do those unresponsive script errors provide any information that can help investigate this, or are there any other troubleshooting information we should ask for from the user?

The logstash link above points to a timeframe that no longer exists in the logs. Here's a new run for the last 12 days - 1e9baad99ca15d901c974831aa70e298-logstash

@artpi is this still a big problem? The original report 4 months ago said it was logging ~2000 times per day, but it looks like now it's closer to 500. Is it worth keeping this ticket open for more investigation?
