Because LINGUAS file is still present at git, the "ug.po" file was never included in the 0.4.4 release tarball and causes the package to fail compilation:
If I'm not mistaken, the solution is to remove the LINGUAS file from git, and do a new release, like 0.4.5
Thanks for reporting this! I guess I should auto-generate that list...
Version 0.4.5 should fix this.
