Workout name is not set

[cuh7b5]

For some weeks the script does not set the name of the workout. Upload is ok but I get the following message:

$ gupload.py -l user pass -a 'test' filename.tcx
2016-07-22 16:41:44,935::UploadGarmin::ERROR::Workout name not set
File: filename.tcx    ID: 1267327236    Status: SUCCESS    Name: FAIL!    Type: N/A

I use python 2.7.12, nothing was upgraded on my system, it simply started to fail.
