Comment 14 for bug 450927

Also finding this error on 0.91pre1_64bit for many extensions:

The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml

Technical details:
DLL load failed: %1 is not a valid Win32 application.
