Description
The following steps cause qgis to crash:
- Load a linestring layer (from PostgreSQL in my case)
- Enable editing on the layer
- Click on the 'move vertex' tool
- Click on the map, well away from the linestring, hold down the left mouse button and move the mouse
- Qgis will crash
The backtrace starts with:
#0 0xb711fab9 in QgsGeometryVertexIndex::back () from /home/gavin/local/lib/libqgis_core.so #1 0x0817ca0c in QgsMapToolVertexEdit::canvasMoveEvent () #2 0xb703fb72 in QgsMapCanvas::mouseMoveEvent () from /home/gavin/local/lib/libqgis_gui.so #3 0xb78734e6 in QWidget::event (this=0x8469388, event=0xbfda7444) at kernel/qwidget.cpp:5703
This is with svn r7668 with the dialog box warning about the snap tolerance disabled. I think that prior to being able to disable the dialog box, a click down and move without selecting a vertex was not possible.
