Can't open Quartz Composer on new updated OS 10.8.3

Question

Hello,
After upgrading yesterday from Snow Leopard to Mountain Lion OS 10.8.3 on MacMini early 2009, I today downloaded correspondent new XCode app from Apple Store to my Application folder.
Tried to open old Quartz Composer.
No way. Error Message:
An exception was raised:
+[QCImageManager registerImageBufferConverterClass:priority:]: "BackdropsImageBufferConverter" is already registered
Then I found Ralph Johns's post on archived thread https://discussions.apple.com/thread/2373658:
"If the timings went Snow Leopard Install then 10.6.2 update the Developers Tools I would try running the COMBO version of the OS Update over what you have.
http://www.apple.com/downloads/macosx/apple/macosx_updates/macosxv1062updatecomb o.html"
So, I downloaded OSXUpdCombo10.8.3.dmg and installed that update.
Then deleted all items from my Developer folder and downloaded new Quartz Composer app, through xcode46graphicstools6938140a.dmg and tried to open it.
-> Same error message.
What can I do?
Thank you for helping,
Michel

Wasn't there an actual crash report?
I didn't see that, screen was as shown

BTW in your first screen shot what happens if you press continue?
Yesterday: I belive that nothing (no answer to mouse call)
Just now: error message disappears, but impossibility to open a new file

Open the Console app, search down the left hand side column until you come to the DiagnosticReports heading, open it and see if there are any crash reports from QC. If so copy and past the first 50 or so lines from it.
Is that what you mean?
