kmplot no longer runs (and uses 100% CPU)

[s3a]

Running it from menu has same problem but to offer something to work with:

deniz@deniz-laptop:~$ kmplot
kmplot(7977) MainDlg::MainDlg: parentWidget->objectName(): "KmPlot"
kmplot(7977) MainDlg::setupActions: KStandardDirs::resourceDirs( icon )= ("/home/deniz/.kde/share/icons/", "/usr/share/icons/")
^C
deniz@deniz-laptop:~$

Earlier on today, it worked perfectly! After playing around excessively with the zooming in and out, I noticed this problem. Please help because this program helps me with school!

Edit: When I run it as root, it works!:

deniz@deniz-laptop:~$ kmplot
kmplot(6753) MainDlg::MainDlg: parentWidget->objectName(): "KmPlot"
kmplot(6753) MainDlg::setupActions: KStandardDirs::resourceDirs( icon )= ("/home/deniz/.kde/share/icons/", "/usr/share/icons/")
^C
deniz@deniz-laptop:~$ sudo -i
root@deniz-laptop:~# kmplot
kmplot(6780) MainDlg::MainDlg: parentWidget->objectName(): "KmPlot"
kmplot(6780) MainDlg::setupActions: KStandardDirs::resourceDirs( icon )= ("/root/.kde/share/icons/", "/usr/share/icons/")
root@deniz-laptop:~# logout
deniz@deniz-laptop:~$

As user it still uses 100% CPU and doesn't really launch while as root, it launches without a problem!
