[issue21872] LZMA library sometimes fails to decompress a file

Ville Nummela added the comment: My stats so far: As of writing this, I have attempted to decompress about 5000 downloaded files (two years of tick data). 25 'bad' files were found within this lot. I re-downloaded all of them, plus about 500 other files as the minimum lot the server supplies
