It could have a better handle of the no-options and invalid options. Instead of a error can be something like:

apport-retrace
No options given. Please, use apport-retrace --help to get a complete list of options.

or

Invalid option. Run apport-retrace --help to get a complete list of options.

if no option is given apport prints the following:
$ apport-retrace
Usage: apport-retrace [options] <apport problem report | crash ID>

apport-retrace: error: incorrect number of arguments; use --help for a short help

it tries to do exactly that in karmic and lucid too, but seems to crash with that UnicodeError for some reason.

Ok, after some debugging it turnes out that python2.6 sys.stderr.write() can't handle unicode characters that aren't converted to bytes first:

sys.stderr.write(str(u'\xfc'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 0: ordinal not in range(128)

sys.stderr.write(u'\xfc'.encode('utf-8'))

So it could be a bug in python too?

Possibly, I'm not an expert about python, and the guys in #python said that 2.6 write() doesn't support unicode and you have to convert it. I'm not sure if that's just a workaround or the intended behaviour. 2.7 works fine with unicode btw. and output in python 3 seems to work differently.

I can still replicate with "python2.6 /usr/bin/apport-retrace", but python2.7 apparently has this fixed. As 2.7 is the default in natty, I'm closing this now. Thanks!
