Bug 325627

Application: kmplot (1.2.1)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.1-29.g2fa222d-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

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

1) create a (cartesian) plot, e.g. f(x) = sin(x)
2) let the mouse pointer follow the values in the plot (by clicking into it near the plotted graph)
3) delete the function
-> kmplot crashes

The crash can be reproduced every time.

-- Backtrace:
Application: KmPlot (kmplot), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
