v.in.dlg

Help,

I have an ascii dlg soils file.

Using v.in.dlg , the code reads in the ascii dlg file ok, then crashes
in v.dlg.to.digit -

dursoil

<dursoil>

    nodes: 656
    areas: 286
    lines: 865
  unknown: 0

STEP 1: Open all necessary files
STEP 2: Read dlg header
STEP 3: Analyze
STEP 4: Write digit header
STEP 5: Write digit Lines and attributes
pid 17859 (v.dlg.to.digit) was killed on an unaligned access, at pc 0x40bd5c
sh: 17859 Bus error - core dumpedERROR((null)): Could not convert
binary dlg file:........

Possible input format error ???

any suggestions are appreciated

thanks
