I cannot find your github issue about that. Could you paste a link, if you managed to find 10 minutes of your precious time to post the reproduce-scenario during your 1 year long struggle?
It's been reported a at least once already, see[1]. However, I don't see why I am required to create an issue before I am allowed to complain. OwnCloud has tons of open issues on GitHub, I'm sure there are doing their best to solve them already.
