[Apport retracing service (apport)]

Thank you for taking the time to report this crash and helping to make Ubuntu better. This particular crash has already been reported and is a duplicate of bug #423208, so is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

This is most likely still a duplicate of 423208 but it's really annoying when the retracer marks a bug as a duplicate of a non-public bug. Now I don't even get the stack attached to this bug so I can't even take a quick look to see if it's something which is easy to fix.

[Martin Olsson (mnemo)]

The only reference to ".Element" that I can find is inside src/timerapplet/core/PresetsStore.py:

    def _save_presets(model, file_path):
        root = et.Element('timerapplet')
        root.set('version', '1.1')
        ...

--------------------------
...and in this context "et" is defined as:

try:
    from xml.etree import ElementTree as et
except:
    from elementtree import ElementTree as et

[Martin Olsson (mnemo)]

Not surprising, the relevant documentation for these modules points out both have valid Element() factory functions:
http://docs.python.org/library/xml.etree.elementtree.html
http://effbot.org/zone/pythondoc-elementtree-ElementTree.htm

So I guess it's some sort of packaging bug.

[Martin Olsson (mnemo)]

This little sample works on my machine and it prints "1" followed by "2" (python --version returns "Python 2.6.3"):

try:
        print "1"
        from xml.etree import ElementTree as et
        print "2"
except:
        print "3"
        from elementtree import ElementTree as et
        print "4"
x = et.Element('timerapplet')

I made the bugs duplicates of 445549 instead and freed up 423208. Not that
the other bugs would be more helpful in finding the stacktrace in question...

Kind regards,

xml.etree.ElementTree is shipped with Python 2.5 by default, so why does this break on Python 2.6?

[Kenny Meyer (knny-myer)]

Cannot reproduce this error on a virtual Ubuntu 9.10 with Python 2.6 *and* Python 2.5.

In both cases xml.tree.ElementTree is shipped by default with the Python (as it should be).
