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
