[Qgis-developer] Broken code after upgrade to QGIS 1.4

[Matthew Denno]

Hello List,

Quick question.  The following piece of code seemed to always work
before upgrading to 1.4, but now it seems to fail with this message:

The program has unexpectedly finished.
/home/matt/Programming/DelaunayIntersection/DelaunayIntersection
exited with code 0

Any ideas with what the cause might be?  Any help or direction would
be greatly appreciated.

Matt


CODE:

bool is_valid_shapefile(QString myLayerPath,
                        QString myLayerBaseName = 0,
                        QString myProviderName = "ogr",
                        QString myPluginsDir = "/usr/lib/qgis")
{
    // Instantiate Provider Registry
    QgsProviderRegistry::instance(myPluginsDir);

    //Open the shapefile vector layer from file
    //fails here
    QgsVectorLayer * mypVectorLayer  = new QgsVectorLayer(myLayerPath,
myLayerBaseName, myProviderName);

    return mypVectorLayer->isValid();
}
