I'm getting this when trying to commit to SVN this morning:
svn: Commit failed (details follow):
svn: MKACTIVITY of '/svnroot/matplotlib/!svn/act/6b28eb9b-4b59-0410-81bc-d80e6be37be8': 403 Forbidden (https://matplotlib.svn.sf.net)
Googling suggests this occurs when the developer doesn't have write permissions (not the case here), or using http rather than https (also not the case).
Filed a bug here:
Anyone else experiencing this?
