I can confirm that I am facing this issue on my install as well. 32-bit Maverick, upgraded from Lucid. Searching in Activity Journal works, but no results in Nautilus-elementary.
Searching in nautilus-elementary, then backing out of the search (alt-left) when it failed to find anything actually crashed nautilus-elementary a couple of times, but I am not sure if this is due to the same bug, and I can't consistently recreate the crash.
