I can reproduce this on gtk2 as well as gtk3. Fedora 21.

It happens with Snippet82 as well. 

Although I noticed that the error occurs when you hover you mouse over the tab **name** and then move it away from the tab name, either to the 'x' or down to the tab content area or any where above the CTabFolder. 

I'm currently investigating a DND issue with CTabFolder:
Bug 457476 - [GTK3] DND drop operation does not work in Eclipse fast-view 
I'll keep this issue in mind.
