PDFs with errors

[Johann Casper Ferdinand F]

In the same light as some of my other recent posts, I note that there are a very few PDFs with errors, at least according to the Multivalent tools. I've checked these and they appear to work normally in Adobe reader despite the error:

IMSLP15385, IMSLP15427, IMSLP15479 - cause tool.pdf.Validate to crash

IMSLP21957 - locks up tool.pdf.Validate in an infinite loop.
