By accident I saw that Gatherer got updated to 3.0, 3.0.1 and then 3.0.2 -- but WUU wasn't showing that, so I updated Gatherer manually.
Since then Gatherers version is shown as "#This is Gatherer v3.0.2##" (# is actually a square being a CRLF), and everytime I check for new versions and Gatherer is highlited, wxpython throws s stdout/stderr-window containing this:
Traceback (most recent call last):
File "WUU.py", line 2675, in OnListItemSelected
File "WUU.py", line 1672, in RefreshInfoPanel
File "Wurm.pyc", line 575, in _getChangelogFilename
ValueError: too many values to unpack
Version is 1.6.446 and I just did a clean install of WUU.
