Note that MRD_HREAD is not printing an error message, but an
"informational" message.
Below is the relevant code within MRD_HREAD

; Check that there aren't improper null characters in strings that are
causing
; them to be truncated. Issue a warning but continue if problems are
found.

w = where(strlen(block) ne 80, Nbad)
if (Nbad GT 0) then begin
if ~keyword_set(SILENT) then message, /INF, $
'Warning-Invalid characters in header'
block[w] = string(replicate(32b, 80))
endif

You might be able to catch the error if you change the /INFORMATIONAL
to /CONTINUE.
