Crash when sorting by folder name

[andrej1919]

Bug Description
Czkawka crashes when attempting to sort or group duplicates by directory. (Similar crash can occur when I try to select files by path or with Regex.)
The crash occurs regardless of the dataset size and has been reproduced consistently on my system. The application exits with a critical GTK error and panics.

Steps to reproduce:

1. Open Czkawka GUI.
2. Scan directories with duplicates.
3. Attempt to sort or group the results by directory in the GUI.
4. Observe that the application crashes immediately.

What I Expected to Happen: The application should sort or group duplicates by directory without any errors or crashes.

What Actually Happened: The application crashes, displaying the following terminal error:

Gtk-CRITICAL **: gtk_list_store_get_value: assertion 'iter_is_valid (iter, list_store)' failed
thread 'main' panicked at ...: Failed to get TreeModel value: ValueTypeMismatchError { actual: <invalid>, requested: gboolean }

**Additional Details:**

Running with RUST_LOG=debug consistently reproduces the issue.
The crash does not occur when listing or sorting duplicates by file size or name—only when sorting by directory.
Cache files were verified to be intact, with no missing or corrupted entries.
Steps Taken:

Verified the issue with a variety of datasets and duplicate groups.
Cleared and rebuilt caches to rule out cache-related issues.
Tested with both cached and non-cached duplicate sets.

Other Notes:
This issue seems related to the gtk_list_store_get_value function, possibly indicating a mismatch in data type handling within the GUI’s tree model when grouping by directory.
Running the app in debug mode (RUST_LOG=debug) does not avoid the crash.

7.0 fails the same. Here is the way I installed it:

wget https://raw.githubusercontent.com/Homebrew/homebrew-core/68842ccd25bad1aeeb67fdf3eff9d9b8af26cd23/Formula/c/czkawka.rb
brew uninstall czkawka
brew install --formula ./czkawka.rb

6.1 the same:

wget https://raw.githubusercontent.com/Homebrew/homebrew-core/586a7a117cc023e1080a260639cd1fa19d4d1f95/Formula/c/czkawka.rb
brew uninstall czkawka
brew install --formula ./czkawka.rb
