Description

After the migration from XE 2.5 to XE 5.3, the Space List in user's watchlist has been corrupted with a heading comma, for example like this:

,xwiki:XWiki,xwiki:Main

this causes an error that prevents the header section of the page to be displayed. The stacktrace produced by the section is the following:

Error number 4001 in 4: Error while parsing velocity page /templates/menuview.vm
