Do you mean some case where this happens and the trace it does?

Here is a log exhibiting the kind of issue aforementioned [1] (got
with this defconfig [2] on top of master + this patch)
In this case, /usr/lib/python2.7/site-packages/_xmlplus/xpath/ParsedAbbreviatedRelativeLocationPath.py
and /usr/lib/python2.7/site-packages/_xmlplus/xpath/ParsedAbbreviatedAbsoluteLocationPath.py
cannot be compiled due to syntax error, so only their corresponding
*.pyc are missing in the final target fs.
