Comment 1 Alan McGovern 2012-12-03 11:04:36 UTC
Weirdly enough, a few patches were committed several months ago to fix all known causes of this issue but they have not yet made it to a MonoDevelop release. They should be part of the 3.1.x series once they are released. For now the only solution I can offer is either to not use submodules in your project or to disable git support inside MonoDevelop using the Add-in Manager.
