            Bug ID: 368398
           Summary: crash when moving pop-up note beyond page border
           Product: okular
           Version: 0.21.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: kadlecf at fzu.cz

If a pop-up note (created via the Review | Pop-up Note tool) is moved beyond
the page border, okular crashes. Ideally, I would wish not only to avoid the
crash, but also to be able to move the pop-up note to another page (in a
multiple-page view)

Reproducible: Always

Steps to Reproduce:
1. Open a file, usually I use pdf.
2. Create a pop-up note
3. Move the note (ctrl-mouse) beyond the page border.

Actual Results:  
Okular crashes.

Expected Results:  
1. Note stays at the page border; or,
2. In a multi-page view, the note is moved to another page, if the mouse cursor
is dropped to a location on that page.

Application: okular (0.21.3)

Qt Version: 4.8.6
Operating System: Linux 3.16.7-42-desktop x86_64
