Error undefined method `has_tags' or `id' for nil:NilClass during rails db:seed Question

When running rails db:seed I get some errors without any further explanation.

CloseReason: Created 0, skipped 5
User: Created 0, skipped 1
PostFlagType: Created 0, skipped 4
PostType: Created 0, skipped 5
ReactionType: Created 0, skipped 3
SiteSetting: Created 0, skipped 57
Got error undefined method `has_tags' for nil:NilClass. Continuing...
Ability: Created 0, skipped 7
PostHistoryType: Created 0, skipped 12
Got error undefined method `id' for nil:NilClass. Continuing...
WarningTemplate: Created 0, skipped 3
TagSet: Created 0, skipped 2
License: Created 0, skipped 5

Are they critical? Should I do something?

I tried to setup QPixel again and while I could avoid another error, this one persists. I gathered more information by adding to the rescue clause of db/seeds.rb

puts "#{e.class}: #{e.message}"
puts e.backtrace.join("\n")

and got

In the database SELECT * FROM post_types delivers

Maybe that helps finding the cause and judging the severity of the issue.

I found a issue on Github from August 21 that is related to seeding, but contains only little information at the moment.
