#2814: digitizer crashes, leaves vector broken
-------------------------------+-------------------------
 Reporter:  harrikoo           |      Owner:  grass-dev@…
     Type:  defect             |     Status:  new
 Priority:  normal             |  Milestone:  7.0.3
Component:  wxGUI              |    Version:  7.0.2
 Keywords:  digitizer, vector  |        CPU:  Unspecified
 Platform:  Unspecified        |
-------------------------------+-------------------------
 I have yet to build a case where this manifests consistently, but it has
 appeared several times. I describe some features of the defect:

 1. Usually happens when crossing lines and boundaries: moving vertices
 around so that existing lines cross, thus creating new lines/areas. But
 not always; I haven't found a regular pattern yet.

 2. digitizer crashes immeadiately, as does wxgui

 3. topology is not built. After v.build, the coordinate file is larger
 than it should be, and v.build reports that the vector contains lots of
 incorrect boundaries. v.build is unable to fix these, and using v.clean
 does not seem to help either.

 4. the vector cannot be opened in the digitizer, as the digitizer crashes
 immediately upon opening the corrupted vector.

 5. the data in the vector can be salvaged with a judicious used of 'v.edit
 tool=delete' or by using 'v.extract' with right criteria to move the
 correct features to a new vector.

 I can send a coor file of a vector demonstrating the results of this bug
 to someone interested in seeing it.
