Commit list periodically jumps to top

[LinqLover]

Steps to reproduce:

• Select a repository with many commits (more than 1 screen page)
• Select the first commit
• Scroll down to page 2 or further
• Wait for approx. 10 secs
• The list jumps back to the top

I did not check this, but this is likely an issue in the Trunk, as I think I could already have seen something similar in Squeak Inbox Talk. :-)
