Try the following patch (derived > from there). The patch has now been tested on one 3.4-RELEASE machine and (by tege@swox.se) on two different 3.3-RELEASE machines. The patch seems to fix the problem and we suggest that the fix is incorporated on the stable branch and that pr/16568 be closed. To all involved parties, thanks a lot for all the good work that you spent to resolve this issue, THANKS! Keep up the good work, Björn -- _ _ ,_______________.
