Excerpt from the corrupted document

A document that was edited multiple times across various computers and also using MS Word, got corrupted while being saved from LO Writer. When Writer tries to open the document now, the following error is displayed:
"""SAXParseException: '[word/document.xml line 2]: Attribute w.val redefined', Stream 'word/document.xml', Line 2, Column 446548(row, col)."""
MS Word displays a similar error, and both programs fail to open the file.
Please note that the column number does not apply to the attachment below; the original file should not be published online, also because it is quite large.

The redefined w:val attributes occurs 4 times in total, all in a single word. There are recorded changes: replacing single letters of that word and also making the whole word italic. Further, there is a comment attached to the word.

I am reporting this bug for a friend of mine who asked me to repair the broken document. For that reason, I cannot give much details on the problem. I failed to reproduce such a corrupted document in LO -- that can mean either that this bug got fixed, or that I just did not find the right series of steps.

(Anyway, I hope reporting this problem helps track down the issue, if it has not been fixed yet.)

Hi Adam,

Thanks for the report. I confirm the problem on a daily from 20160517.
However, the question is if this can be solved / prevented.. So set to NeedInfo.

Ciao - Cor

File corrected

After having decompressed the file then used this
tidy -utf8 -xml -w 255 -i -c -q -asxml on word/document.xml
I recompressed the file and could open it on LO built from master sources updated today.
Could you give it a try?

Sorry, no, it doesn't help, unless you can attach the source document from MSO, before it was saved with LO, preferably a minimum test needed to reproduce.

@telesto: no need to link different errors that start with "SAXParseException" unless they are the same, which doesn't seem to be the case here.
