I didn't reproduce this myself. The information I got was from a crash
dump file sent for TSVN and what the user told me. So I don't know
whether the --keep-local is the reason for the crash. But as the user
said, there was a tree conflict on that folder and he tried to remove
the folder to get rid of the tree conflict. So the folder already was
marked as conflicted.
