Comment 27 for bug 553779

In the interest of saving one round-trip, I tried adding -Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.2 to /etc/eclipse.ini

Now the effects are the same in a new and existing workspace. The xulrunner view ("My RadRails") is empty, which I don't mind at all. When closing it, I get an "XPCOM error -2147467262" alert (exception trace below), followed by an "unhandled SWT error" dialog box, suggesting that I turn off Eclipse. Everything seems to be working well if I ignore the error.

All in all, I think the eclipse.ini patch is a win (I can use Eclipse now) and I'm grateful to get to this state. I'm happy to collect more information if that helps.

Thank you for investigating this bug!
