[Qgis-developer] QGIS creating defective shape-files?

[Marco Lechner - FOSSGIS e.V.]

Hi,

I'm having a weird problem with some shape-files. May be it's a QGIS- or
a ArcGIS Bug:
I'm managing a lineshape exported from an ArcGIS geodatabase into a
lineshape. Extracts (also done with ArcGIS) are edited in QGIS (by the
way: the editors find it much more comfortable to use QGIS for that. I
just have to use ArcGIS for extensive Topology testing). We are using
QGIS 1.2.0 unstable (Codestand 10965M on Windoof), because of some fixed
Bugs from earlier versions that hit us.
The problem is:
The shapes seem to be without any problem using QGIS, but when I add it
to ArcMap some Lines disapear at a specific Zoomlevel.
The problem disapears by exporting the shape from ArcMap into a new shape.
I'm not sure how to find the "guilty party" (well, I know who is the
guilty one in general). Is it QGIS creating dirty shapes? Or is it just
a Bug in ArcGIS? Honestly it's quite hard to get any support from ESRI.
Does anybody who is just in the Code able to say, if it could be QGIS or
ArcGIS doing something wrong?
