Description khagaroth 2011-12-08 14:57:39 UTC 
If Legacy Filters are not installed, Document Converter doesn't work. It completely fails to launch, just throwing a meaningless (that is, for normal users) error message and jumps to the code that caused the error.

Possible solutions:
if legacy filters are not installed, disable Document Converter menu entry
or
display a meaningful error message explaining the dependency instead of just erroring out and jumping to faulty line in code editor
or
fix Document Converter to work without legacy filters, conditionally disabling functionality that depends on them

Reproducible on Win7 Swedish with LibreOffice Beta 3. 

It seems to fail when trying to create the service com.sun.star.comp.office.BF_MigrateFilter 

I attach a screen-shot with the error message.

I haven't looked at the code for the code for the service and it is probably there it should be fixed but a quick and dirty solution in BASIC is to create a function:

Function createBF_MigrateFilterIfPossible()
Dim oService
	On Error GoTo RTError
	oService = createUnoService("com.sun.star.comp.office.BF_MigrateFilter")
	getBinFilterCompIfItExists = oService
	Exit Function
RTError:
	createBF_MigrateFilterIfPossible = Nothing
End Function


Then replace the line:
oBinFilterComp = createUnoService( "com.sun.star.comp.office.BF_MigrateFilter" )

with:
oBinFilterComp = createBF_MigrateFilterIfPossible()

oh huh, *registered* but not actually installed. Current scenarios handled are "registered and installed" and "unregistered and not installed"
