today I had the same problem...

Invalid database handle      0 on line 990.
Invalid or incomplete DXF input -- drawing discarded.

After a few hours of useless struggles with DXF references
http://images.autodesk.com/adsk/files/dxf_format.pdf

I solved just editing dxf with a text editor and deleting ALL dxf
sections, except for "ENTITIES" one

so now, my DXF starts with

0
SECTION
 2
ENTITIES
 0
TEXT
 1
53.0

and ends with:

...
TEXT
 1
54.0

ENDSEC

I know it's a brutal hack but it works fine for me...
Any better hint from developers?
