我一直使用xwatermark和draftmark都没有问题，直到今天，我用它们创建的 LaTeX 文档无法编译为 PDF。我正在使用 TL 2014 运行 Kubuntu 14.04，这是我上周自己安装的。
这是一份测试文档，xwatermark注释掉代码后可以正确编译。编译失败（调用xwatermark）会创建一个.WMX文件，必须先删除该文件，注释掉的版本才能编译。

我看到了两个错误。其中一个是这样的：
ERROR: Argument of \Hy@setref@link has an extra }.
--- TeX said ---
<inserted text>
\par
l.49 \end{document}
--- HELP ---
From the .log file...
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
另一个是这样的：
\xwm@secstopagerange {1000}{1}
我很困惑。我今天更新了 TL（2014）。
