Did a little more testing, in all cases gdebi-gtk worked fine, - either installed; installed with available dependencies; didn't install because deps couldn't be met
So the only package it crashed on was the above, "bzr_2.4.1-1ubuntu1_all.deb" which it should have said it couldn't install because a later version of 'python-bzrlib' was either installed or was the only version available to be installed, tested both ways.
So at least here this crash only occurs when a dep is the wrong version, either installed or available for install
