I hit this yesterday too. GDB-MI doesn't seem to be able to handle
what GDB calls "multiple" breakpoints. i.e. a breakpoint that GDB sets
on every overloaded function that matches an expression. The problem
is that the MI output has an extra field - "type" only on the "parent
breakpoint", while GDB-MI expects to find it even on "child
breakpoints".

I've attached a patch. Could you check if it works for you too?

PS: While at it, I also cleaned up what gets displayed in the absence
of fields in MI output. The breakpoint table now shows "" instead of
nil.
