[FATAL] Git service failed: nested transactions not supported

I am receiving the following results in the GitIntegration Logfile:

2013-07-31 10:39:31 GitIntegration [FATAL] An exception occurred in the Git connector while getting commits:

It should be noted there are 37 Repositories in the configuration.xml. On inintial run, it scanned and worked properly with no issues, after quite a few runs it seems to start showing this message for one particular repo. Upon shutdown and restart the message appears for an additional 4 repositories in the logfiles. I removed the repository cache and restarted, same results apply.

This is Repeatable. Start the Service, it scans fine. Stop the Service, Make a commit to the git repo. Restart the Service, and immediately you have these errors. Additionally I have been getting these as well, but are cleared by deleting the local cacheed repo:

This change has corrected the issue. I now consider my bug report resolved and closed. (I recompiled with your patch changes and attempted same actions as before. It no longer dumps on me)

Glad to know. It took a little longer to write a test to confirm the bug and fix. I've now posted new binaries on the app catalog for all to enjoy.
