Hi guys. I’m following the GETTING STARTED TUTORIAL.
I’m stuck in the 4th step. When I click “Open project”, nothing
happens.
In the error log sector appears that message:
“Unhandled event loop exception”
plug-in:
org.eclipse.ui
Thanks for your help
Are you running on Mac or Windows? Does it help to restart the editor? Do you see any additional output in the Error Log window?
Thanks for response britzl. I’m running it on Linux. This is the entire output log:

Have a look at this potential solution: https://www.eclipse.org/forums/index.php/t/235996/
Great! now Defold crashes when I click “Open Project” ha ha. The error became another xD.
I just ran this command:
apt-get install libwebkitgtk-1.0-0
I removed the library
apt-get remove libwebkitgtk-1.0-0
and came back to the first error xD
What kind of error did you get the second time?
Are you on 64bit Linux?
No man. It’s Elementary Os freya 32 bit (ubuntu-based distro)
I solved the second error. I came back to the first one: “When I click “Open project”, nothing happens”.
"Unhandled event loop exception" 
When I say: “nothing happens” means that the “open project window” doesn’t open
Oh yeah! I solved the problem 
. I just:
/opt/ folder./Defold-linux.gtk.x86/Defold.ini fileAnd I can open the “open project window” Woooooo!
Nice! Let us know if you run into any other issues!
Thanks buddy! I hope to help other “defolders” with their issues also
Thank you very much for documenting this. I’m using Elementary OS too and got to solve the issue just as you said. Using chrome instead of mozilla so I also had to change that in the .ini file.
There’s a file called Defold-linux.sh that is shipped with the Linux (64bit) version of Defold. If you start Defold using that script instead of the Defold binary it should work, in addition to mapping a XulRunner, we’re making some changes to the desktop environment to better support the Defold editor.
