For added strangeness that will possibly help you track this down I have
the following snippets of my attempts to work around this bug in the
GNOME Do plugins code:

This snippet builds:
Services.Application.RunOnThread ( () => {
	/* Mono 2.4 bug hack
	 * This can't use using () due to some crazy-wierd scoping problem.
	 * See https://bugzilla.novell.com/show_bug.cgi?id=516676 for details.
	 */
	IEnumerable<IFileItem> temp = uploads;
	UploadPool uploadQueue = new UploadPool (tags);
	try {
		foreach (IFileItem photo in uploads)
             		uploadQueue.EnqueueUpload (photo);
					uploadQueue.BeginUploads ();
	} finally {
		uploadQueue.Dispose ();
	}
});
This snippet: 
Services.Application.RunOnThread ( () => {
	/* Mono 2.4 bug hack
	 * This can't use using () due to some crazy-wierd scoping problem.
	 * See https://bugzilla.novell.com/show_bug.cgi?id=516676 for details.
	 */
	UploadPool uploadQueue = new UploadPool (tags);
	IEnumerable<IFileItem> temp = uploads;
	try {
		foreach (IFileItem photo in uploads)
			uploadQueue.EnqueueUpload (photo);
		
		uploadQueue.BeginUploads ();
	} finally {
		uploadQueue.Dispose ();
	}
});
fails, with "error CS0165: Use of unassigned local variable `uploads'"
