Subversion: Another Subversion operation is already in progress

Hi

I get this very often on the Mac on Xamarin Studio. Currently on version 4.0.9 (build 12). It usually occurs the second time I run update.

MonoDevelop.VersionControl.Subversion.SubversionException: Another Subversion operation is already in progress. at MonoDevelop.VersionControl.Subversion.Unix.UnixSvnBackend.TryStartOperation () [0x0003a] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl.Subversion.Unix/MonoDevelop.VersionControl.Subversion.Unix/SvnClient.cs:1023 at MonoDevelop.VersionControl.Subversion.Unix.UnixSvnBackend.Status (MonoDevelop.VersionControl.Repository repo, FilePath path, MonoDevelop.VersionControl.Subversion.SvnRevision rev, Boolean descendDirs, Boolean changedItemsOnly, Boolean remoteStatus) [0x0002a] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl.Subversion.Unix/MonoDevelop.VersionControl.Subversion.Unix/SvnClient.cs:496 at MonoDevelop.VersionControl.Subversion.SubversionBackend.GetDirectoryVersionInfo (MonoDevelop.VersionControl.Repository repo, FilePath sourcepath, Boolean getRemoteStatus, Boolean recursive) [0x00006] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl.Subversion/MonoDevelop.VersionControl.Subversion/SubversionVersionControl.cs:170 at MonoDevelop.VersionControl.Subversion.SubversionRepository.OnGetDirectoryVersionInfo (FilePath sourcepath, Boolean getRemoteStatus, Boolean recursive) [0x00000] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl.Subversion/MonoDevelop.VersionControl.Subversion/SubversionRepository.cs:116 at MonoDevelop.VersionControl.Repository.GetDirectoryVersionInfo (FilePath localDirectory, Boolean getRemoteStatus, Boolean recursive) [0x00006] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl/MonoDevelop.VersionControl/Repository.cs:202 at MonoDevelop.VersionControl.Views.StatusView.<StartUpdate>m__2 (System.Object ) [0x00018] in /Users/builder/data/lanes/monodevelop-lion-monodevelop-4.0.9-branch/f9c5c24e/source/monodevelop/main/src/addins/VersionControl/MonoDevelop.VersionControl/MonoDevelop.VersionControl.Views/StatusView.cs:415
