I installed the 0.9.15 yesterday and cloned a local repository. The original repo is also an SVN repository. Today I synced some changes via SVN and committed them to the original HG repo. The clone did not show the incoming/outgoing markers in the left-hand panel. Pulling fetched nothing. Pulling from the command line worked.
Sorry, I know that's a bit vague! I have no further insights into what's going on there.
