ValueError: expected only letters, got u''

[brianmay]

I have been told this is due to the latest python-babel package.

This was reported against Debian, and reproduced against version 1.8.0.

Thanks for reporting this !

I have added compile-catalog as a target in tox and travis so we get alerted on this in the future.

Cannot quickly see why it only PT fails. I might just remove the translation to get the build working again.

p.s. I would love to get the debian build files into the repository if we can.

Should be fixed in 1.8.1

found some other issues, so not yet able to close this

Should be fixed in the upcoming 1.8.1 release.

If Debian wants to patch the older version, this patch should help:
