When adding a new data composition in xfburn, the title of the tab 'Data composition 1' is not translated. There is a string 'Data Composition' in the translation, this should be a case error since 'Audio composition 1' is translated successfully.
Thanks for your report, it's now been fixed. http://git.xfce.org/apps/xfburn/commit/?id=75a9291b961b52b3aaae19fa0c2f049054a555c0 The existing translation for "Data composition" that was still present as a comment, has automatically been reused :) Best regards, Mike
