[Solved] Oracle BPM Studio throws XPCOM error on Ubuntu 10.04

I've just installed Oracle BPM Studio 10gR3 for Linux x86 in my Ubuntu 10.04 LTS. After running the install package I started to use it when this exception was thrown when I tried to open a "presentation" tab:

XPCOM error -2147467259
org.eclipse.swt.SWTError: XPCOM error -2147467259
    at org.eclipse.swt.browser.Mozilla.error(Mozilla.java:1296)
    at org.eclipse.swt.browser.Mozilla.create(Mozilla.java:266)
    at org.eclipse.swt.browser.Browser.(Browser.java:109)
    at fuego.ui.peer.swt.SwtBrowser.createBrowser(SwtBrowser.java:137)

 After an intensive search in Google about this exception, I read that it should be a XULRunner version problem. So I searched in repositories for XULRunner packages and I installed the following one:

sudo apt-get install xulrunner-1.9.2

Finally, I edited the OraBPMStudioHome/eclipse/eclipse.ini file and I added the following line.

-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.2.12

Once fixed this problem, I haven't had any other exception in BPM Studio :)
