Silverlight 5.1 crashes Wine in SeaMonkey 2.31

[Keith Bowes]

It worked fine in SeaMonkey 2.30, but it started crashing upon the upgrade to SeaMonkey 2.31. If I downgrade to SeaMonkey 2.30, it works again. Silverlight 5.0 works OK in SeaMonkey 2.31, so I've downgraded the plugin instead of the browser. From a web search, it seems that people are having the same problem in Firefox 24, but I couldn't find the problem already reported here or in Mozilla's bug tracker.

I've isolated the problem. In the config file, the following line causes the problem:
replaceJavascript = window.navigator = __pipelight_navigator

Everything works fine when I replace it with
replaceJavascript = window.navigator.userAgent = __pipelight_navigator.userAgent

Hi,

you can basically comment these javascript lines if you are using a proper user agent switcher. Nevertheless, this seems to be a SeaMonkey bug since a browser should never crash because of javascript. Looks like SeaMonkey does not properly handle the case when the window.navigator object is exchanged with a different object.

I would recommend to put the same javascript snippet into a regular HTML file and see whether SeaMonkey crashes when you try to open it. If this is the case you should fill a bug in their bug tracker.
