Description

I'm experiencing problems running the following script in QGIS 1.8:

---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---

from qgis.core import *
from PyQt4.QtCore import *

inFileName="/tmp/test.csv"

url = QUrl.fromLocalFile( inFileName )

capaImportada = QgsVectorLayer( QString.fromAscii( url.toEncoded() ),
"testLayer", "delimitedtext" )

pr=capaImportada.dataProvider()
pr.featureCount()

QgsMapLayerRegistry.instance().addMapLayers( [capaImportada] )

---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---8<---

In QGIS 1.8, pr.featureCount() shows the correct number of features (7L) but the feature table always shows only the last record. The layer metadata also seems correct. Tha same happens both in Windows or Debian.

The script works fine in QGIS master but that will require to adapt all the code of my plugin.

An alternative coud be to use the OGR driver:

capaImportada = QgsVectorLayer( inFileName, "ogrTest", "ogr" )

but I need the ability to ignore an arbitrary number of lines at the beginning of the file, but I cannot find any way to do it with OGR.

Does anybody know of any other workarounds?
