I can confirm this in g.gui.vdigit as well, even without letting one area
cut another. It is enough that the newly digitized area is within snapping
distance of the other. This is easiest to see when you use a fairly high
distance (working on the landsat images in the NC example data I used
1000m). The debug messages are similar to Markus'.
As g.gui.vdigit is a python script I don't know how to debug this with gdb
(I get "No executable file specified"). Any hints ?
