[Bug 989252] Re: pylint-gui throws exception when running file or package

[Hans Joachim Desserud]

>Does this still needs to be fixed?

Thanks for the reminder. :) I checked now and I am no longer able to
trigger this issue with pylint 1.1.0-1 on Ubuntu 14.04 or later. This
newer version presumably contains the upstream fix, so I'm closing this
as fix released.

However, pylint 0.25.0-1ubuntu1 on Ubuntu 12.04 is still affected and
this is a rather serious issue. If someone need a fix for the bug for
12.04, please perform as much as possible of the SRU Procedure [1] to
bring the need to a developer's attention.  I may be able to help out a
bit here with preparing a debdiff with the attached patch. :)
