FileChooser crashs when opening large folder

FileChooser crashes when it tries to open folder with large number of files. The system is a Vista 32 bit with 1.7.0_07-b10. See hs_err for details.


Steps to reproduce:

* open the file chooser.
* navigate to a large folder (845 files) on a hard disk (on a SSD it work without crash)
* change to details view
* order after the file size. Now you can see the first graphical artefacts
* scroll in the list
