on my most recent crash there was a little more information than before. after the memory map in the shell where the crash occurred there is now this message:

^CTraceback (most recent call last): File "/usr/local/bin/gnuradio-companion", line 63, in <module> ActionHandler(args, Platform()) File "/usr/local/lib/python2.7/dist-packages/gnuradio/grc/gui/ActionHandler.py", line 70, in __init__ gtk.main()

and the new from gdb:

warning: .dynamic section for "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/_gnuradio_core_runtime.so" is not at the expected address (wrong library or version mismatch?)
