cElementTree will raise a SyntaxError on XML parsing errors, while
ElementTree will raise ExpatError.  This makes changing between the two
a bit more problematic than it could be. See for example
https://lists.canonical.com/archives/bazaar/2006q3/017491.html

ElementTree 1.3 raises a ParseError, which is subclassed from
SyntaxError, which will improve the situation when it's merged, but
cElementTree should be adjusted to raise the same error.
