.desktop files with custom icons

Question

I created an app and custom icon for it. I succesfully installed and stuff and when I add a path to the Icon path into the .dekstop file like this:

Icon=/usr/share/icons/hicolor/64x64/resize.svg

it works fine but with Icon=resize it does not. My app icon is just the default one.

I installed the icons with the following command in the cmakelists.txt and I checked the icons too, they are copied so everything should be fine. What do I miss?

install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/16/resize.svg DESTINATION share/icons/hicolor/16x16/apps)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/24/resize.svg DESTINATION share/icons/hicolor/24x24/apps)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/32/resize.svg DESTINATION share/icons/hicolor/32x32/apps)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/48/resize.svg DESTINATION share/icons/hicolor/48x48/apps)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/64/resize.svg DESTINATION share/icons/hicolor/64x64/apps)
install (FILES ${CMAKE_CURRENT_SOURCE_DIR}/data/icons/128/resize.svg DESTINATION share/icons/hicolor/128x128/apps)

As I understand from the documentation I read on the subject Icon=resize should work fine.

Apparently it does not work in your case. (Maybe you should ask someone from you Linux distribution in a bug report or on a mailing list).

Icon=resize.svg is more specific. (See comments on the question)
