With more info from the user:

The problem I had was as follows:

1. I was looking at the Results dialog.
2. I changed View to look only at results.
3. I enabled Delta view.
4. I sorted by Time.
5. I selected all the delta time rows where delta time <> 0.
6. I asked to remove from results all selected items.
7. The items did NOT get removed from the results (this appears to be the beginning of the bug).
8. I tried to select one of the results that I had asked to be removed.

When I did step 8, I got the error.

Everything up to #7 is repeatable (i.e., the selected results do not get removed).

A similar issue of lists not refreshing happens with the Add Directory feature. I added the root directory of an external drive. I then changed one of the subfolders on this drive from Normal to Reference. I realized that I had done this backwards, so I tried to change the Root from Reference to Normal. It wouldn't take. I then tried to change some of the other folders, and nothing seemed to respond. So, I removed the folder, and then re-added the same folder, and the Reference/Normal switch had changed.

I couldn't reproduce the issue, but I haven't tried very hard so far.
