Bug#983851: meld: Python error on svn checkout

[alberto]

Package: meld
Version: 3.20.2-2
Severity: normal

Dear Maintainer,

when I excute "meld ." on a svn branch, meld it is not able anymore to show
the differences between checkout and local modfications.

It just display the local foldr name as if it can't find anything to compare
with.

Executing in terminal gives the following traceback:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/meld/task.py", line 110, in iteration
    ret = task()
  File "/usr/lib/python3/dist-packages/meld/vc/_vc.py", line 277, in refresh_vc_state
    self._update_tree_state_cache(path)
  File "/usr/lib/python3/dist-packages/meld/vc/svn.py", line 188, in _update_tree_state_cache
    for entry in (t for t in target.getchildren() if t.tag == "entry"):
AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getchildren'
