Summary: BUG: 388228 Diff applies to Applications/17.12, and should be easy to merge to master. It's kept quite minimal as suggested by Albert. Albert also suggested to add a dedicated unit test and I'd agree, but am not yet sure how to do it. The original bug involves several classes, including UI: Document, Page, AddAnnotationCommand, PageView, PageViewAnnotator, MouseAnnotation - to name a few. So a test for the exact bug scenario would become a bigger integration test rather than an isolated unit test. The other approach would be to do a real unit test on MouseAnnotation. But again, MouseAnnotation has nasty dependencies (e.g., needs a parent PageView) which I'd have to mock. Any ideas? I'd be interested in a discussion on this topic. Test Plan: # Load a document (e.g. [[ http://www.philipebert.info/resources/WhatMathematicalKnowledgeCouldNotBe.pdf | linked PDF from bug report ]]) and enable highlight toolbar (F6). # Create highlight annotation. # Move the view port so that the annotation position is right beside the highlight tool icon. # Move the mouse over the annotation, and then horizontally left until you reach the tool icon; it's important to stay over the highlight annotation as long as in viewport. # Press ctrl-z for undo. # Click on highlight tool, move right into the document, create new highlight annotation. # Okular doesn't crash.
