Conflict Resolution Blanks Title
When performing conflict resolution via the Wiki URL Manager, undeleted and unrenamed articles have their titles cleared. On subsequent edits, the user will receive an error for an empty title. This doesn't cause serious problems on the article because the thread DM fails on a blank title, but the revision column no longer contains a valid title.
Fixed for the next build. This is now also handled in VaultWiki 4 so we don't expect the title to be set during imports.
