Sometimes the log cache gets corrupted. We haven't found out why or when
this happens yet. But one thing that helps prevent such situations is to
add the path %appdata%\TortoiseSVN\logcache to the exclude list of your
virus scanner.

If you ever encounter this again, you don't have to clear the log cache
from the settings dialog or manually: in the log dialog, hold down the
ctrl key and then hit F5 to refresh - that will also clear the cache and
do a full refresh.
