segfault when unable to fetch token

One user reported the following (though it looks like they are using old/unknown distro provided packaging):

Need to see if I can replicate this in 3.0.22...I suspect I need to drop network packets mid-flight to do this.

i have the same issue - looks like it has a 500 error then the next attempt dumps a segfaut.
