[Qgis-user] Load buffer by percentage plugin python error

[Luís Campos Paulo]

Hello to all
I couldn't install the buffer by percentage plugin on the QGIS 2.6, and gives a error message - the plugin is broken.
Then when I start the QGIS it gives the following window message:


Couldn't load plugin BufferByPercentage due an error when calling its classFactory() method



Traceback (most recent call last):

Can anyone help me to fix this problem, so that I can use the buffer by percentage plugin?
Thank you
