Finder crashing every time we do a second search on a network drive.

We just clean installed Mountain on 2 iMac's in our small business environment. There are approximately 30 other macs on the network ranging from 10.5.8 to 10.8. There are also 3 servers, a 10.5, 10.6 and a 10.7 server.

Both iMacs running Mountain Lion are crashing any time we perform a second search on the 10.5 server and report the following error.

8/21/12 12:22:59.045 PM
com.apple.launchd.peruser.502[122]
(com.apple.Finder[447]) Job appears to have crashed: Segmentation fault: 11

By second search I mean that the search result comes back fine when we open a new Finder winow and perform a search, but if we just leave the search results window open and perform a second search... Finder crash.

Any thoughts?
