Executable and source of the hang program

When in editing mode, for example on google.com, if I move the carret from right to left using the keyboard over a link it will hang. When using the mouse, seems to be fine. To reproduce, just put the carret on the right of a link and press the left keyboard key continuous. The problem is ONLY on windows systems. On ubuntu it works fine. I've used the binaries from the midori browser. The bug appears on every version of webkit (tested on 1.1.5 ... 1.2.4)

After examining the sources, I couldn't find any setExternalResourcesRequiredBaseValue implementation. Can this be the cause ?
