I've been running this code for a long long time without problems -

	oDoc = StarDesktop.loadComponentFromURL(sInURL, "MyFrame", 0, args0())

The line of code is contained in a macro which is called from a Button on a Base form. The purpose of the macro is to create a document  and then convert the document created to a pdf.

The aboove code now fails with a message box  that contains this text -

BASIC runtime error.
An exception occurred 
Type: com.sun.star.lang.IllegalArgumentException
Message: Unsupported URL <file:///home/alex/Documents/testoffice//BlueMerged0.odt>: "type detection failed".


The above code works quite happily in LO  5.1.5.2

This is the code in context


sub convertToPDF(strInFile AS String, strOutFile As String)
	writeToLogFile(time & " : " &"convertToPDF")
	
	Dim Dummy() 
	Dim sInUrl As String
	Dim sOutUrl As String
	Dim oDoc As Object
	dim dispatcher as object
	
	dim args0(0) as new com.sun.star.beans.PropertyValue
	args0(0).Name = "Hidden"
	args0(0).Value = True 
REM Remove full stops from name



	sInUrl = ConvertToURL(strInFile)
	oDoc = StarDesktop.loadComponentFromURL(sInURL, "MyFrame", 0, args0())
	
	sOutUrl = ConvertToURL(strOutFile)
	
	dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
	document = oDoc.CurrentController.Frame
