Build Identifier: I20100608-0911

While working with a proprietary gdbserver that generates threads lists for a target, an exception is thrown:
java.lang.NullPointerException
	at org.eclipse.cdt.debug.internal.ui.disassembly.dsf.DisassemblyBackendCdi.setDebugContext(DisassemblyBackendCdi.java:147)
	at org.eclipse.cdt.dsf.debug.internal.ui.disassembly.DisassemblyPart.updateDebugContext(DisassemblyPart.java:1798)
	at org.eclipse.cdt.dsf.debug.internal.ui.disassembly.DisassemblyView$1.selectionChanged(DisassemblyView.java:66)
	at org.eclipse.ui.internal.AbstractPartSelectionTracker$1.run(AbstractPartSelectionTracker.java:119)
	at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42)
	at org.eclipse.core.runtime.Platform.run(Platform.java:888)

The actual line causing this issue is:
result.frameLevel = ((CStackFrame)((fTargetContext.getTopStackFrame()))).getLevel() -  fTargetFrameContext.getLevel();

getTopStackFrame returns null and the function fails.

Reproducible: Always

Steps to Reproduce:
Unfortunately requires our proprietary gdbserver/debug configuration.
If this can not be solved without, let me know and I'll see what can be done.
