Subject: [PATCH] shellEntry: Disconnect handler on destroy
|
|
|
477568 |
|
|
|
477568 |
Actors will get unmapped on destroy, so unless we disconnect from
|
|
|
477568 |
the notify::mapped signal, the handler will run one last time and
|
|
|
477568 |
try to access methods/properties on the invalidated actor.
