We've been passing data->location as the @url argument of
|
|
|
0a59fa |
osinfo_tree_create_from_location_async_helper(), freeing it and trying
|
|
|
0a59fa |
to g_strdup() it as the new content of data->location.
|
|
|
0a59fa |
|
|
|
0a59fa |
In order to avoid doing so, let's set the data->location only once, in
|
|
|
0a59fa |
the first caller of osinfo_tree_create_from_location_async_helper(), as
|
|
|
0a59fa |
its content is always going to be the same doesn't matter the treeinfo
|
|
|
0a59fa |
format to be used with.
