Bug 335413

Application: okular (0.19.1)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

With 2 okular instances opened (one with a 'unique' instance (it does not allow other tabbed documents) and the other as a 'regular' instance), I closed the'regular' instance and okular crashed (the 'unique' instance was lost afterwards as well)
The 'unique' instance contained my LaTeX output/PDF, but I do not think it was being rebuild (and thus reloaded at the same time).

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
