Kepler SR 1 (4.3.1): e4 key bindings will be removed by BindingToModelProcessor [message #1137183]

I have migrated an e4 RCP application to the most recent Kepler 4.3.1 release.

The RCP application has dependencies to org.eclipse.ui and therefore also to org.eclipse.ui.workbench.

While doing a regression test after switching to the 4.3.1 target platform, I noticed that key bindings defined in the e4 application model were broken.

I tracked the problem down to the org.eclipse.ui.internal.BindingToModelProcessor which deletes all key bindings which do not have the tag "type:user". This includes also the bindings defined by my e4 application model.

This behavior has been introduced by a fix to bug 406003 (sry, can't post eclipse links because of forum restrictions).

The attachment contains the e4 sample application project (modification: added org.eclipse.ui dependency) that demonstrates the problem. Just startup the application in Kepler 4.3.1 and try to open the about dialog (CTRL+A) -> the key binding won't work.

Is this new behavior for e4 RCP applications intended? If so, how to correctly define key bindings in the e4 application model?

Problem is even worse. The removal of key bindings affects all plugins in an application. Even the Live Editor cannot be opened anymore.

PS: I also noticed that tracing key bindings doesn't work. Perhaps this is connected.

So no one knows how to do it correctly? Certainly adding the tag "type:user" to the key binding can not be a proper solution. It works quite good but it seems to be a misusage of the "type:user" tag, as it should be used for user defined key bindings.

Should I file this as a bug?

I've created a workaround using a custom model processor that simply adds the tag "type:user" to all key bindings, see this Gist:
