How to import a CSV with list field labels using Feeds? I have a content type "Car". The fields are "Title", "Body" and "Gearbox". The "field type" of the field "Gearbox" is "List (integer)", and the "Allowed values list" for this field (in the "key|label" format) are:

1|manual
2|automatic
3|semiautomatic


I want to import content from a CSV file using a standard node import with Feeds. My CSV is as follows

GUID,Title,Body,Gearbox
1,Lexus NX,blabla,automatic
2,Porsche Cayenne,bloblo,manual


On importing this CSV file, the value for "Gearbox" is not copied over. Instead, it appears as empty in the content. If I replace the values for "Gearbox" by their keys, as in this modified CSV file

GUID,Title,Body,Gearbox
1,Lexus NX,blabla,2
2,Porsche Cayenne,bloblo,1


then it works correctly.

Nevertheless, I'm not the end user and I need to leave the CSV file in its more human-friendly form that uses the "labels" instead of the "keys" (as in the original CSV above).

How can I do this? I.e. how can I have the import recognize the labels "manual", "automatic", etc instead of their corresponding keys?
It seems that this is a known issue. There is a patch at https://www.drupal.org/node/2006810
