GIT commit message is null

[jd...@jdege.us]

I'm running Ubuntu 11.10, with MonoDevelop 2.6 and Git support 2.6.0.

I created a new solution, with a C# console project, and with Git
Support enabled.

From the top menu, I did Version Control ==> Commit Solution.

I got the "Commit Files" dialog, which listed the changed files.
Below the grid listing the modified files, there was a label "Commit
message:", with nothing following it.

I clicked "Commit", and received an error:

System.ArgumentException: Commit message must not be null or empty!
Parameter name: message
at MonoDevelop.VersionControl.Git.GitRepository.Commit
(MonoDevelop.VersionControl.ChangeSet changeSet, IProgressMonitor
monitor) [0x00000] in <filename unknown>:0
at MonoDevelop.VersionControl.CommitCommand+CommitWorker.Run ()
[0x00000] in <filename unknown>:0

I looked in Preferences ==> Version Control ==> Commit Message Style,
and I see text in the Preview.

Any ideas?
