Tor Browser crashes in LogMessageToConsole()

Just tried to search "let's encrypt" on https://github.com. It crashes the Tor Browser Hardened 5.5a5-hardened without any error message.

The error is reproducible (at least on my two machines), but no other search term seems to trigger a crash.

BTW, is there a way to get any logs from the crash?
