Fix crash and hang while renaming

A new version of my patch. This fixes both:
- the crash when renaming a file through the popup dialog
- the hang when renaming many files at once (e.g. using mv)

For the remaining crashes (while using mv command), please apply https://github.com/jlindgren90/thunar/commit/9c6dbb1dae70.
