I downloaded http://download.kde.org/stable/calligra-latest/calligra-2.7.5.tar.xz and the changes in this commit: http://quickgit.kde.org/?p=calligra.git&a=commit&h=5611c5ce3f7079b5c84826943384019776d7ad69 doesn't seem to be. The files "filters/sheets/csv/kspread_csv_{ex,im}port.desktop" are still using their old names rather than "filters/sheets/csv/calligra_filter_{csv2sheets,sheets2csv}.desktop" resulting in an error, 'sheets(12943)/csvfilter CSVFilter::convert: Invalid document mimetype  "application/x-kspread"', being displayed when trying to open a CSV file or create a new one and save it.

Reproducible: Always

Steps to Reproduce:
1. Create new, blank document in Sheets.
2. Save as "example.csv"
3. Get error: 'sheets(3109)/csvfilter CSVExport::convert: Invalid document mimetype  "application/x-kspread"'

OR

1. Open existing CSV file
2. Get error 'sheets(3109)/csvfilter CSVFilter::convert: Invalid document mimetype  "application/x-kspread"'
Actual Results:  
I get a popup error stating that the file couldn't be saved or opened, in the latter case due to not being implemented ("Not implemented").

Expected Results:  
Saved or opened the file with the CSV filters.
