Error parsing the XSLT:

System.OverflowException: Value was either too large or too small for an Int32. at System.Convert.ToInt32(Double value) at System.Double.System.IConvertible.ToInt32(IFormatProvider provider) at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) at System.Xml.Xsl.Runtime.XmlQueryRuntime.ChangeTypeXsltArgument(XmlQueryType xmlType, Object value, Type destinationType) at System.Xml.Xsl.Runtime.XmlQueryContext.InvokeXsltLateBoundFunction(String name, String namespaceUri, IList`1[] args) at (XmlQueryRuntime {urn:schemas-microsoft-com:xslt-debug}runtime) at Root(XmlQueryRuntime {urn:schemas-microsoft-com:xslt-debug}runtime) at Execute(XmlQueryRuntime {urn:schemas-microsoft-com:xslt-debug}runtime) at System.Xml.Xsl.XmlILCommand.Execute(Object defaultDocument, XmlResolver dataSources, XsltArgumentList argumentList, XmlSequenceWriter results) at System.Xml.Xsl.XmlILCommand.Execute(Object defaultDocument, XmlResolver dataSources, XsltArgumentList argumentList, XmlWriter writer) at System.Xml.Xsl.XslCompiledTransform.Transform(IXPathNavigable input, XsltArgumentList arguments, XmlWriter results, XmlResolver documentResolver) at System.Xml.Xsl.XslCompiledTransform.Transform(IXPathNavigable input, XsltArgumentList arguments, TextWriter results) at umbraco.macro.GetXsltTransformResult(XmlDocument macroXML, XslCompiledTransform xslt, Dictionary`2 parameters) at umbraco.presentation.umbraco.developer.Xslt.xsltVisualize.visualizeDo_Click(Object sender, EventArgs e)

here is the part of code which fails:

<xsl:for-each select="umbraco.library:GetMedia($currentPage/galleryImageFolder, true())/Image">
  <xsl:if test="umbracoFile !=''">
      <li>
        <img src="/imageGen.ashx?image={umbraco.library:UrlEncode(umbracoFile)}&amp;height=100&amp;constrain=true" alt="{umbracoFile}" />
      </li>
  </xsl:if>                
</xsl:for-each>
