Hi Jonathan, 1. As Matthias suggested, after you send a kill signal, you can go back to the gdb prompt and type bt to see the backtrace. 2. You QGIS 2.18 is not starting with a specific project, right? (The one with style by category). The project file is readable (hum... if XML is readable!).

Several years ago I tried to generate Voronoi polygons around a number of points. I think I was using QGIS version 2.10. The result was not satisfactory (Nearest Distance interpolation in raster gave better results). There was one polygon with no generator point in it while an adjacent polygon

Hi Jonathan, The most interesting part in GDB becomes visible as soon as you type "bt" after a crash (I think the same if you kill it but no guarantee). Thanks Matthias On 03/23/2017 06:11 PM, Jonathan Webb wrote: > Hi Jorge, > > I uninstalled all my plugins & that project won't even open now.
