Yes, the bug is the one reported in that email. It has been filed as bug https://bugs.kde.org/show_bug.cgi?id=246755 (I set it in this RR).
The problem was that the value was passed without quotes as parameter to the the function in libxslt. But on the other side it is not used, because the output of the stylesheet is stored in a string and then written in a file (see transform function in xslt.cpp), so it's pointless to pass it.
