Description Frank Reininghaus 2013-03-07 21:42:50 UTC 
Related to bug 315210, which is about a similar issue that happens when deleting expanded folders with filtered children.

Reproducible: Always

Steps to Reproduce:
1. In Details View, expand a non-empty folder.
2. In the filter bar, enter something that makes the children of the expanded folder disappear.
3. Collapse the folder, e.g., by clicking the arrow next to it.
4. Clear the filter.
Actual Results:  
The children reappear. In master, we even get a crash because KFileItemModel::lessThan tries to dereference the dangling "parent" pionter of the ItemData.

Expected Results:  
The children should not reappear.

Remove filtered children if the parent folder is collapsed

This is analogous to commit e053ecdcd57cc39fdcbc314fc8dd22c8b9dbdd4f,
which fixes the same problem for the case that the parent folder is
deleted.
