PDF extraction fails when specific image is present in file

### Bug description

When running extraction on a PDF containing a specific embedded image, the process fails.
If I remove the image from the PDF and re-run the extraction, it works correctly.

### Steps to reproduce

1. Configure the converter with the following pipeline options:

```
# Configure OCR options
pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.table_structure_options.do_cell_matching = True

# Set accelerator to CPU to avoid pin_memory warnings when no GPU is available
pipeline_options.accelerator_options = AcceleratorOptions(
num_threads=multiprocessing.cpu_count(), device=AcceleratorDevice.AUTO
)
pipeline_options.images_scale = 1.0
pipeline_options.generate_page_images = True
pipeline_options.generate_picture_images = True
pipeline_options.ocr_options = EasyOcrOptions(force_full_page_ocr=False)
pipeline_options.do_picture_classification = True
pipeline_options.do_picture_description = False

# Create converter and process document
self.converter = DocumentConverter(
allowed_formats=[
InputFormat.PDF,
],
format_options={
InputFormat.PDF: PdfFormatOption(pipeline_options=pipeline_options),
}
)

# Only process the first page
self.converter.convert(pdf_file_path, page_range=(1, 1))
```

2. Run extraction on the problematic PDF (attached separately).
3. Observe failure.
4. Edit the PDF to remove the image.
5. Run extraction again → works fine.
