Attached the Java source file from the stack trace.

As far as I can tell, ToolTipManager.insideComponent is set to null while insideTimerAction.actionPerformed executes.

Maybe related to the fact that the Buttons are dynamically hidden?

Closed as duplicate of #8921.
OpenJDK6 + Ubuntu => Duplicate of #8921

Immediate and recommended solution: upgrade to OpenJDK 7 as we plan to drop support for Java 6 anyway.
