    The labplot 1.5.1 closes unexpected every time I try to do interpolation. Does anyone recognize the problem?

    This is waht the Labplot- KDE Crash Handler says

      this problem occurs if thew data is unsorted or not uniq (in x). I have fixed this problem
      by (optionally) sorting and removing points with same x-value.
      This feature will be available in version and 1.6.0.pre3.

      Thanks for reporting.

      This seems to be an incorrect call to a gsl function.
      Can you tell me how to reproduce this problem?
      Maybe you can send me a description or your project
      file so i can check it out.

      This happends everytime I try to do a interpolation, it doesn't matter what data I use or what kind of interpolation i try to do.
      For exampel
      I press ctrl + = to make a new spreadsheet (I think you call it spreadsheet, I got Swedish language on Labplot)
      I type in data so it look like this
      X Y
      1 1
      2 2
      3 3.1
      4 4.2
      5 5
      6 5.8
      7 7
      8 8.1
      9 9.1
      10 9.9

      I make new 2D-diagram, ad the data to a new curve. press alt+I to do a interpolation but when I press the OK buttun does the program close down, without warning.

      Maybe this info helps you

      martin@Martin:~$ labplot -v
      Qt: 3.3.6
      KDE: 3.5.5
      LabPlot: 1.5.1

      and a project that crash when I try to do a cspline (or any other interpolation)
