G'day,
I've rebuilt and installed GNU Radio svn-7461 as of today on a system running
python-2.4.4 and swig-1.3.31. It still crashes when started and stopped a few
times, three times in this particular case, with message shown below. This
was using example noisy_sinusoid.grc.xml application provided by the GRC
package. This is reproducable at will. Note the "TypeError: 'str' object is
not callable" and the message just prior to the coredump.

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
