Sorry, but you're wrong. Both this construct will catch ImportError and
don't block Explorer. The messages you see:

Unable to load plugin 'svn'. It requested API version (2, 0, 0) of
module <module 'bzrlib' from
'/usr/lib/python2.6/dist-packages/bzrlib/__init__.pyc'> but the minimum
exported version is (2, 1, 0), and the maximum is (2, 1, 0)
Unable to load plugin 'git'. It requested API version (1, 18, 0) of
module <module 'bzrlib' from
'/usr/lib/python2.6/dist-packages/bzrlib/__init__.pyc'> but the minimum
exported version is (2, 1, 0), and the maximum is (2, 1, 0)
Unable to load plugin 'gtk'. It requested API version (1, 17, 0) of
module <module 'bzrlib' from
'/usr/lib/python2.6/dist-packages/bzrlib/__init__.pyc'> but the minimum
exported version is (2, 1, 0), and the maximum is (2, 1, 0)
Unable to load plugin 'rebase'. It requested API version (1, 17, 0) of

is generated by bzr itself when it loads plugins at startup, even before
command "explorer" is started.
