I aborted the dialog "Fetching tree conflict information" because that takes over half an hour on my working copy, which is not acceptable. But afterwards, I get an error when I click on "Accept incoming deletion", see screenshot.
Is this intended? I don't think that it should be necessary to get the tree info just to accept an incoming deletion.
Also, I don't understand why it takes so long to fetch the tree info, but that's most likely not TSVN's fault. And I don't understand why SVN searches from rev 4800 back to the rev 1 of my repo, when the branch was created around rev. 4500. There cannot be any tree conflicts prior to rev. 4500... Who is querying the tree info, TSVN or SVN?
