Branch: refs/heads/master Author: LarsGit223 lars_paulsen@web.de Committer: LarsGit223 lars_paulsen@web.de Date: Wed, 20 Feb 2019 20:18:03 UTC Commit: 7058a5dd8f086ae762abb2cb9f689951125f96cd https://github.com/geany/geany-plugins/commit/7058a5dd8f086ae762abb2cb9f6899...
Log Message: ----------- scope: prevent usage of invalid iters (GtkTreeeIter)
This is done by checking all results from calls to 'gtk_tree_selection_get_selected()'. Additionally some initializations have been moved behind parameter checks in 'scptreestore.c' to prevent crashes in case (still) an invalid iter would be passed as an argument.
The changes in function 'stack_entry()' fixed #824.
