Exception in RemoveOperationProgressFromContent

[gkronber]

I got an exception in RemoveOperationProgressFromContent:

"No progress is registered for the specified content."

This happened when I was uploading jobs to Hive (in multiple tabs concurrently).

Relevant section of code:

    /// <summary>
    /// Removes an existing <see cref="ProgressView"/> from the <see cref="ContentView"/>s showing the specified content.
    /// </summary>
    public void RemoveOperationProgressFromContent(IContent content, bool finishProgress = true) {
      if (InvokeRequired) {
        Invoke((Action<IContent, bool>)RemoveOperationProgressFromContent, content, finishProgress);
        return;
      }

      IProgress progress;
      if (!contentProgressLookup.TryGetValue(content, out progress))
        throw new ArgumentException("No progress is registered for the specified content.", "content");

      if (finishProgress) progress.Finish();
      foreach (var progressView in progressViews.Where(v => v.Content == progress).ToList()) {
        progressView.Dispose();
        progressViews.Remove(progressView);
      }
      contentProgressLookup.Remove(content);

    }
