I found this bug using Nightly build r48004.

To reproduce:
 - visit
http://www.bosch-home.nl/sitemap/quick-links/service/reparaties.html?rw=true
 - about halfway the page in the wide center column, press the "Online
Reparatieformulier" hyperlink; a form will open in a new window
 - next to the "E-Nr.*" input field, press the button with the downwards arrow
symbol; a popup will open with a error message (because you didn't fill out the
necessary fields)
 - by now, WebKit has already frozen more or less, e.g. you can't switch to
another window anymore
 - close the popup with the close button or with the "Sluit Venster" hyperlink;
after about a second WebKit crashes.

Backtrace is in the attachment.
The system console reports that Webkit exited abnormally because of a bus
error.
