Description

It seems not possible to delete raster layers stored in geopackages on Windows from the "Browser" panel with QGIS 3.3.0-master (d99d506e75): a warning message box pops up with the text "Layer URI is malformed: layer [layer URI] cannot be deleted!".

I guess the problem is in https://github.com/qgis/QGIS/blob/master/src/providers/ogr/qgsgeopackagedataitems.cpp#L360-L364

QStringList pieces( uri.split( ':' ) );
    if ( pieces.size() != 3 )
{
      errCause = QStringLiteral( "Layer URI is malformed: layer &lt;b&gt;%1&lt;/b&gt; cannot be deleted!" ).arg( uri );
    }

In fact a typical geopackage Layer URI on Windows is GPKG:C:/some/path/geopackage_name.gpkg:layer_name so pieces.size() is always 4 on Windows.
