I just ran into this problem as well. For me, it happened when I was using valgrind to debug a program of mine, immediately after I clicked to close my program (but apparently before it had successfully shut down). If you're interested, I can try to get it to reliably produce this error and/or provide the source to my program. This is with gdb 6.3-5 and valgrind 2.4.0-2. The "Attach to debugger ?" line really is the first line of valgrind output I can find; it doesn't seem to be associated with any report of an error condition.
