transcribe error - index -1 out of bounds for length 0

[aum7]

attached file gives me error:
index -1 out of bounds for length 0

i tried scaling down (shrink) the image,
then i got '... with 6 pixel between ... try enlarge image resolution ...'
so the size of original file should be ok

i also tried cleaning / processing the image(s) with

• unsharp mask
• then remove grays
  i get pretty good resulting images, but same error appears

while resolution might be quite big,
in past audiveris (ole! lol) showed popup notification saying 'file to big ...'

original image - 1563 x 2207 px

processed image - 1563 x 2207 px

this is the only image(s) i have trouble with
the rest of my audiveris (ole!) adventure has been a smooth sailing

EDIT: almost complete image is otherwise correctly transcribed / detected
if i export .mxl (or .xml)
and import it into musescore
i get completely blank / empty page

cleaned the image a bit more
now it works as expected

seems top staff
with undefined barlines & time signature
is the root of all evil on this planet (lol, kidding)

EDITh (piaf lol): the other thing i removed manually are side and bottom black lines (probably remnants of scanned book pages)

[aum7]

is there an option to select an area of the image and mark it as unworthy of transcribing ?
tried & searched, could not find

EDIT: of course with [ctrl] for multiple areas selection
