All reports of duplicates of this bug stopped shortly after Weng's proposed fix in comment 3. This fix was included in version 15.12.0 (and even 15.11.80), and the duplicates of this bug reports filed after the release of 15.12.0 were still filed against 15.08.* (when the version was provided). It seems quite obvious that Weng's fix actually solved the problem, so I close here. I gladly reopen if someone stil sees this in version 15.12.0 or later.
