python error on ubuntu 16.04

[cyBea]

Thanks for your extension! Unfortunately it doesn't work for me:

$ python --version
Python 2.7.12

inkscape v0.91
ubuntu 16.04

Traceback (most recent call last):
  File "applytransform.py", line 96, in <module>
    e.affect()
  File "/usr/share/inkscape/extensions/inkex.py", line 265, in affect

  File "/usr/share/inkscape/extensions/inkex.py", line 304, in getDocumentUnit
    p = param.match(svgwidth)
TypeError: expected string or buffer

Maybe it's a bug in ubuntu / inkscape?

Strange, that doesn't look like it's directly related to this extension.. It sounds similar to this issue?

Looks like an issue in v0.91 where the svg root element didn't have a width/height specified

[cyBea]

Yes, you are right! I added
width="100%"
height="100%"
as pointed out in launchpad bug report and the plugin worked without this error. Thanks for your help!

Happy to help!
