Application: okular (0.14.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was opening the PDF file and rapidly pressed the key "2" for "Yellow Inline annotation", then Okular crashed. Same happened, when I rapidly pressed "F6" (to enable "Annotation" bar, that is NOT remembered …), then "2",

The crash can be reproduced every time.

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