As discussed in #2690

Problem stems from failure to handle cases where nested sequences all end at the same point. Previous implementation only closed the current sequence, without considering whether its own parents also needed to close at that point.

I'll be running my battery of tests shortly to confirm this doesn't introduce any issues with current datasets.

OK, tests all check out - though with these changes I am now able to handle more data than previously, which is nice... 😁

Thanks; would likely have taken me a helluva lot longer to figure this one out.

Confirmed correct operation on the provided problematic dataset; beyond that I can only place my faith in the private DICOM test suite that it doesn't break anything else.

Is there any merit in incorporating the data from @timrosenow into that private dataset? Or, as might be possible given your statement, were there existing data in there that are now working given this fix, and so they would not provide any additional utility?
