Dear Andreas,
Life's a bit busy at the moment, but a couple of quick comments:

Correct. It's a GTK+ bug (GTK+ doesn't update its information when the
screen gets rotated) that's really hard to overcome.
Xournal should do very slightly better at it than GIMP and other
programs, because it bypasses GTK+'s event coordinate conversion and
does its own, assuming the aspect ratio of the digitizer matches that of
the screen and the upper-left corner never moves (which of course are
not quite correct, hence the frequent loss of calibration upon rotation).
I have ideas on how to do much better by trying to match core events
with extension events and auto-correcting when things become too far
off, but it's a bit of a hack and will have to wait for now.
For now, perhaps cleanest to just not try to deal with it, and let users
restart after display rotation. I'll be happy to try hacking
at it later.

This has been fixed in xournal's CVS code base. The patch adds an X
error trap around the functions to enable/disable Xinput devices. This
is in xo-callbacks.c, more precisely in on_canvas_enter_notify_event()
and on_canvas_leave_notify_event(). (see how these have changed between
stock 0.4.5 and the CVS).
This is a small enough fix, and given how annoying the crashes are, I
suggest you include it too.
Good luck with everything!
Denis
