Must be related with protobuf. My strokemap_pb2.py (which is generated by
protoc) is using "descriptor.Descriptor" instead. So maybe a different
version of the protobuf compiler was used when generating the file in the
package.

That's the same version I have installed on my system. (MyPaint is working,
but I compile it myself, so I run my own protoc version.)

$ protoc --version
libprotoc 2.2.0
