first i alayw provide some information when storing not a empty array a you did

Thiscomponent.storeToURL( ConvertToURL(sfile), Array( MakePropertyValue("FilterName", "writer8", "ReadOnly", "False" ))

and i allways do convertToURL(myURL) to been sure it's a correct URL (your URL seems corrrect)

Did you played around with

"storeAsURL" and "storeAToURL"

I  do the folowing check
  if fileexists(ConvertToURL(sfile)) then
Thiscomponent.storeToURL( ConvertToURL(sfile), Array( MakePropertyValue("FilterName", "writer8", "ReadOnly", "False"))
                '    bIsNewDoc = False
Thiscomponent.storeAsURL( ConvertToURL(sfile), Array( MakePropertyValue("FilterName", "writer8", "ReadOnly", "False"))
                '    bIsNewDoc = true
            end if

Hope it helps

I am currently experimenting with programming LibreOffice through Python/UNO.
One thing I tried is to create a document, not with the loadComponentFromURL call from the desktop, 
but the route via the XLoadable interface,

After setting up the connection, getting the context, servicemanager, desktop, and XSCRIPTCONTEXT,
the following works:

calcdoc = smgr.createInstanceWithContext("", context)
calcdoc.initNew() # or calcdoc.load(....)
sheets = calcdoc.getSheets()
sheet1 = sheets.getByName("Sheet1")

cell = sheet1.getCellByPosition(0,0)
cell.String = "Hello World"

calcdoc.storeAsURL("file:///Users/piet/TEST/LibreOffice/testcalc.ods", ())

Of course I could have used
calcdoc = desktop.loadComponentFromURL("private:factory/scalc", "_blank", 0, ());
(or with a Hidden=True property)
but I just wanted to experiment with the createInstance version.

Now the above example works perfectly. It creates the spreadsheet, and nothing is shown on the 

Now when I do this with a Writer document:

textdoc = smgr.createInstanceWithContext("", context)

LibreOffice crashes with a segmentation fault. It looks like a null pointer is dereferenced or 
stored into. It seems to be in the event loop. So maybe there is some pointer not properly 

Here is part of the crash report (Mac OS X 10.10.2). This happens both with LibreOffice 
from the installer package and a self-compiled master version.
