Working in Windows (both XP and Vista), when I try to launch gdb debugger (Debug main project), I get the message
"Launching" in the Debugger console window, then nothing happens any more.
NetBeans log file contains the following rows:

GRAVE [org.openide.util.RequestProcessor]
java.lang.StringIndexOutOfBoundsException: String index out of range: 0
	at java.lang.String.charAt(Unknown Source)
	at org.netbeans.modules.cnd.debugger.gdb.GdbDebugger.createShareTab(GdbDebugger.java:1781)

	at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572)

While gdb log file seems to be correct:
