Found a system that has the problems you described. The pfb_clock_sync
seems to be intermittent. It's locking at two different points and so
is off by 1. That's not a huge problem, though it shouldn't be
happening.

The qtgui issue looks like it's with the qtgui.sink_c and qtgui.sink_f
blocks. Everything else works fine. Working on a fix now.
