GRC runtime crash

While using the GNU Radio Companion, I’ve been getting frequent crashes.
They always occur after terminating a flowgraph that has been run from
within GRC. After terminating the fg, there is a few second pause, and
then GRC quits. The error output on the cli where GRC was launched is:

/Users/edwardc/Work/gnu_radio/grc_0.65/src/ActionHandler.py:63:
GtkWarning: Invalid text buffer iterator: either the iterator is
uninitialized, or the characters/pixbufs/widgets in the buffer have been
modified since the iterator was created.
You must use marks, character numbers, or line numbers to preserve a
position across buffer modifications.
You can apply tags and insert marks without invalidating your iterators,
but any mutation that affects ‘indexable’ buffer contents (contents that
can be referred to by character offset)
will invalidate all outstanding iterators
gtk.main()
Bus error

It doesn’t happen every time, maybe 20% of the time.
Has anybody else been seeing this?

I’m running on an Intel MacBook Pro with the following:
OSX 10.4.10
GNU Radio 3.0.3
GRC 0.65
Python 2.4.3_1
Gtk2 2.10.7

Well the error is coming from inside the call to gtk.main(), not
directly from any calls in the GRC source.

When you press the execute button, it does a call to os.system and a
thread waits for os.system to return. When you press the stop button,
you are actually are calling a kill -9 on the running flow graph.

I haven’t heard of this problem (mac os or otherwise). Maybe someone can
make an educated guess?
