Clicking on a message id in a mail, does very weird thing it seems.

Simplified backtrace:

* gnus-read-header("<92164B15-45D1-4D76-9AF6-8E1E098C04BD@telia.com>")
  gnus-summary-insert-by-id("<92164B15-45D1-4D76-9AF6-8E1E098C04BD@telia.com>")
  gnus-summary-refer-article("92164B15-45D1-4D76-9AF6-8E1E098C04BD@telia.com")

read-header returns data, whereas it should probably returns nil. Then a
mail with no info is inserted into the summary.
