I'm new to this list, but I have been mapping in Oslo for a while, using
the username "Håkon". I normally use JOSM, but occasionally I need the
aerial imagery for reference, and so I have used the Java applet. Now I
have tried Potlatch for the first time, and I think I have discovered a
rather serious bug: When deleting a way in Potlatch, it seems that all
points in the deleted way and segments sharing these points are also
I discovered this bug by accident, but have reproduced it with the
following experiment: I created six nodes in JOSM and connected them with
segments making a 'H' shape. I then made three ways for each of the
straight lines making up the H. Then I found this area in Potlatch and
deleted the middle bar of the H:

* ^ *
This way was deleted in Potlatch.
When downloading the area again in a fresh JOSM session, only the four
nodes in the corners of the 'H' were left, everything else was gone...
If anybody wants to have a look at my experiment, I did it near
coordinates 59.9378,10.7435. The way ids created were 4639221, 4639222,
and 4639223 (the last one was the one I meant to delete). (I will of
course delete the remaining nodes soon, since there is not supposed to be
anything in this area...)
By the way: I used shift-delete to delete the way, found this by trial and
error (only pressing delete did not seem to do anything).
