LibreOffice crash

Piet,

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
             else
                 Thiscomponent.storeAsURL( ConvertToURL(sfile), Array( MakePropertyValue("FilterName", "writer8", "ReadOnly", "False"))
                 ' bIsNewDoc = true
             end if

Hope it helps

Fernand
