Moving to JFace for comment. I suspect there is an issue in your plug-in.
From the stack you provide it looks like you are making reentrant calls to your viewer which is some thing we had to protect ourselves. Please not that the viewer is NOT really throwing this exception but it is used only to log informations to findout the reason for it! You are trying to update the viewer while expanding TreeItems. What you can do to make this work is to add a Display#asyncExec() in PluginBrowserComposite.performExpandAction which delays the update call until the expansion is finished.
As per comment #2, doesn't seem to be a bug. I'm closing this as invalid.
