At least you do get error messages.
On my (linux) box simply nothing happens (apart from a little spike in the
CPU applet on some desktop panel) and nothing seems broken. It just won't
work - kill -9 isn't even needed.
The error message in your case seems related to one I posted a while ago
"QObject::startTimer: timers cannot be started from another thread" (2X)
here:
https://mailman.cae.wisc.edu/pipermail/octave-maintainers/2012-August/029811.html
(which in my case didn't hang the GUI - I just had to click in the terminal
to get focus there, and then hit <Enter>)
Maybe a red herring, but do you have win32/moc-QWinTerminalImpl.cc or
unix/moc-QUnixTerminalImpl.cc
in <BUILDDIR>/libgui/ libqterminal ?
