Crash when creating new score using empty custom template
1. Put the "Spiewnik.mscz" in templates folder (.../My Documents/MuseScoreDevelopment/Templates)
2. Create new score
3. Select "Spiewnik" from list of templates
4. Click "Finish"
I bet there's something wrong with this template, but it was created in 2.0 Beta version, so should be fully compatible;
EDIT: I don't understand why my attachment is not listed below, so there's direct link to the file: https://musescore.org/sites/musescore.org/files/issues/piewnik.mscz
