QGIS Crash when trying to load a point layer to georss file

Original Redmine Issue: 10515
Affected QGIS version: master
Redmine category:vectors

---

I'm on a715ce6 debian testing.

And wanted to try to save a point shp file to save as georss (via saveAs), QGIS crashes.

Easy to reproduce: you can even create a memory layer with one point (epsg:4326), save as GeoRSS and QGIS crashes with segfault.

Tried to run with gdb, but only got this backtrace (first saved as geojson, which was ok):

src/core/qgsvectorfilewriter.cpp: 1862: (writeAsVectorFormat) newFilename = /tmp/georss.geojson

Tested also on windows, but there is seems ok.
Anybody can confirm?

I can confirm on Ubuntu/master/64 self compiled.

I can replicate - the crash happens inside the OGR library:

but ogr/ogr2ogr seems ok?

I can happily create a georss file from given shp file with:

ogr2ogr -f GeoRSS output.xml -dsco USE_EXTENSIONS=YES poly4326.shp

(where poly4326.shp is a one polygon in epsg:4326)

Exact trying to save that shape in QGIS crashes it.

I thought to create an issue at GDAL, but I cannot reproduce it with ogr2ogr or so...
