Steps to reproduce:

1.Select a virtual search folder.
2.Open context menu.
3.Select "Properties..." option.
4.Click on "Choose..." button to select folders.

Same problem on WIndows and Xubuntu installation of 2.53.6 release.

Actual results:

Folder selection window is empty.
Cancel button not working.
Ok button not working.
To close you have to click on red cross on the top right side of the window.

Expected results:

Folder selection window should display folder names and selection option.

To the best of my knowledge this is bug 1691208. Should be fixed in current 2.53.8b1 pre and the 2.53.7b1 which is released today.

Files are already there:

Please test and if it works I will close as a duplicate.

2.53.7b1 downloaded, installed and tested on Windows 10 Pro and Xubuntu 18.04 LTS

Folder selection is working again as well as "Ok" and "Cancel" buttons.

Thanks for confirmation. We backed out the offending fix only so the original bug is still open. Adding this one as a duplicate.
