While I think your point stands, these tricky files are a real gold mine for the authors of the doc-importer.

I have a .doc of mine, I liked to use as a test case. I also opened a bug report with the old file a while back. Every year I would open it and print it. Last year it came out with only one 2mm variation in a certain tricky area - which I consider good enough.

So this is a done topic for me and my needs.

I highly encourage everyone who has such a real world file to file a bug report. It is being worked on, albeit slowly.
