From Bug 349736 comment 12:

"When I use GDB 7.0 or 7.1, I get:

   ctxt:       gdb[1].proc[42000].threadGroup[42000]
   context:    gdb[1].proc[].threadGroup[]

This is a problem I ran into before in Bug 336890.  But I missed the scenario
of thread filters.  I'm surprised your ctxt variable has the 42000 threadGroup
and proc set...

All this works properly with GDB >= 7.2, but apparently no so much with olders
GDBs."

This situation makes using thread filters completely deactivate a breakpoint.  The reason is that the threadGroupId is not set when we first create a breakpoint, but it is set when we first set the thread filter.  Since the two contexts don't match, the breakpoint is not installed on any threads.
