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.

If a directory starts with ".", it is interpreted in a wrong way by libxslt with an error like:
-------------------
XPath error : Invalid expression
/home/kde-devel/.cache5/khelpcenter/help/__home__kde-
devel__kde__share__doc__HTML__en__kioslave__file__index.docbook
^
runtime error
Evaluating user parameter outputFile failed
-------------------
This is an old issue, it was "solved" on windows by not compiling that code, but I suspect that the issue has been in UNIX systems too for a long time.
Another way to solve the bug is quoting the value of the parameter with '...', replacing:
params.append(qstrdup(parser.value(QStringLiteral("output")).toLocal8Bit().constData()));
with something like
QString quotedOutput = "'" + parser.value(QStringLiteral("output")) + "'";
params.append(qstrdup(quotedOutput.toLocal8Bit().constData()));
but anyway in this case the name of output file is not used, or I can't find any occurrence in the stylesheets.
The stylesheet is applied and the name of the file is used only after to write the generated XML (see tranform() function).
A similar patch can be applied to kdelibs/kdoctools too (same codepath).</pre>
