Description Saikrishna 2014-04-16 17:35:14 UTC 
Application: kalgebra (0.11)
KDE Platform Version: 4.13.0
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:
I had opened KAlgebra and entered a 3D function to be plotted. I went up to the 3D Graph menu to save the image as a graph. After clicking the save button in the dialog box, KAlgebra crashed. The crash is not specific to a function.

The crash can be reproduced every time.

-- Backtrace:
Application: KAlgebra (kalgebra), signal: Segmentation fault
