Steps to reproduce:
1. Take a screenshot, save it to Pictures. (Works.)
2. Create a subdirectory under Pictures, say Pictures/Test
3. Take a screenshot, save it to Pictures/Test (Works.)
4. Take a screenshot, try to save it directly under Pictures.

What happens:
The directory chooser always picks the ’Test’ subdirectory.

What I expect to happen:
To be able to choose ’Pictures’ as the directory to save my screenshot in.

Workaround:
In the directory chooser, click the pen icon to edit the path. Navigate to parent directory of ’Pictures’. Click to edit the path, make sure you delete the trailing slash (and anything thereafter) from after ’Pictures’, hit enter.

Additional notes:
Maybe this is a general bug of the directory chooser, but without looking, I haven’t come across other apps that make use of it to verify it’s not just Gnome Screenshot that’s affected.
