[BUG] Renaming files with regex doesn't work

[alex13lopez]

Hi, when renaming multiple files of the torrent using regex the preview works fine but when hitting the "Replace" button it gives an error and doesn't actually rename the files. Here's a video demonstrating the issue:

Also for some reason cannot resize columns and it they get collapsed under each other when renaming files too as you can see in the video.

It happens too when renaming without regex, for instance when renaming the root folder of the torrent.
