Subject: [PATCH] pyg_value_from_pyobject: support GArray
|
|
|
|
This commit adds support for marshalling
|
|
a python list (or other sequence) returned
|
|
from signal handlers to GArray, if necessary.
|
|
|
|
This parallels the implementation written
|
|
to marshal to (the now deprecated) GValueArray.
|
|
|
|
This fixes a crash in rhythmbox as seen downstream here:
