since drKonqi doesn't give useful backtrace I tried to run kgrapheditor in gdb. Resulting backtrace shows that the GraphViz is crashing, not kgrapheditor/viewer. Interesting thing is that the file can be processed in dot without problems. kgrapheditor(8390) KGraphViewer::DotGraphView::loadLibrary: ' "file:///home/lukas/enblend.dot" ' kgrapheditor(8390) LoadAGraphThread::loadFile: [New Thread 0x7fffe8bd3710 (LWP 8394)] kgrapheditor(8390) LoadAGraphThread::run: Program received signal SIGSEGV, Segmentation fault.

Hum, for me it crashes in Qt code, when the fish eye view wants to get info about items to display. If I deactivate the FEV, it can display the graph and navigate with scrollbars, but if you put the mouse in the view, then it crashes. I think it is a Qt bug. I will open a bug report at Qt.
