Name resolution?  If Ethereal tries to resolve an IP address in the
capture, and the name server is being unresponsive (or if it's not in
DNS and the next method your OS falls back on is slow - e.g., NetBIOS
inverse lookups, on Windows, if the IP address doesn't belong to a
machine running NetBIOS), Ethereal can become unresponsive until the
name resolution completes, and if the next name resolution has the same
problem, it could take a while to read the capture.  (Yes, a *long*
while - don't assume that, just because it's unresponsive for a long
time, it's necessarily permanently locked.)

Try disabling network name resolution when you start the capture, and
see if it still happens.
