Huh, weird -- I've never encountered that. Top of stack is: https://github.com/mholt/timeliner/blob/b54071f0080f1565a33725d3e59a1035c4eebf8b/oauth2.go#L57

Do you have a chance to dig in a little more as to why? I'm afraid I won't have time to work on it for a while :(

This seems to be caused by the fact that OAuth2AppSource() is never set by loadConfig() in main.go. In the absence of a config file, loadConfig() returns nil.

LE: This happens if you omit to specify a config file.
