[Qgis-developer] Crash with new Label-Plugin

[Andreas Neumann]

Hi Martin,

Actually I was wrong - I apologize. I investigated further. It is only one
layer that causes the crash, other layers seem to work fine.

I have all my data in Postgis, including the one that causes the crash. I
then tried to save the specific Postgis layer to an ESRI shapefile. After
that I could label the polygons fine from the shapefile.

Then I checked the Postgis table against empty or invalid geometries with
the ST_IsEmpty() and ST_IsValid() Postgis functions - I didn't see any
empty or invalid geometries.

I will make the Postgis table available on my server tonight for testing.
I wonder what is wrong with this specific table.

Thank you,
Andreas
