Missing and Bad Anchor in Help Browser throws NPE

Reported by: Hb--- Owned by: team
Priority: normal Milestone: 19.02
Component: Core Version: latest
Keywords: trac wiki help browser anchor Cc:

Description (last modified by Hb---)

In De:Help/Concepts/Object, first paragraph, the link Linien aims formerly aimed to the anchor #WaysAnchor. That anchor is intentionally missing for the purpose of this report. Clicking the link will throw the Null Pointer Exception shown below. Anchors were last dealt with in #15985.

Additionally the same NPE occurs when the anchor is created with [=#Myanchor] and has no content inside the brackets. Trac recommends this in WikiFormatting#SettingAnchors. Trac generates the HTML code <span class="wikianchor" id="Myanchor"></span> which is fine for common browsers. But not for our Help system.
