Comment 1 for bug 435654

Strange.

It looks like the c-format is only available in the zh_CH po file.

Aron, can you please request a po download from Rosetta, manualy delete the c-format and they reupload it.
You can also delete all X-Launchpad headers and upload it as upstream version.

Please contact the zh_CH upstream translator and ask him to also fix this problem upstream.

This is the Romanian file found in the source package
