Hi,
I'm currently facing test failures from the python2-urwid package
required to build wicd. The errors are:

[Message part 5 (text/plain, inline)]
I'm using GuixSD with ext4 partition and kernel Linux 4.9.5. The
package definitions are from git master. The system itself is using git
master from about a month ago.
lfam or #guix said he could reproduce the issue with Linux 4.9.13 on a
ext4 fileystem but not on a btrfs one.
I could not reproduce the issue myself on an Ubuntu 14.04 running Linux
4.2.0 with a ext4 partition .

Sounds reasonable to me.

Applied, thanks!
