After setting a custom column's field name to a display-filter conditional, an
assertion failure occurs at
http://anonsvn.wireshark.org/viewvc/trunk/epan/column-utils.c?revision=36527&view=markup#l251


To reproduce:

1. Open a pcap file (to cause the crash after step 6)
2. Go to Preferences > User Interface > Columns
3. Click Add button
4. For "Field type", choose "Custom"
5. For "Field name", enter "ip.dst || ip.addr"
6. Click OK (or Apply) button
7. Observe the crash and the error message that prints on stdout

This also crashes in Ubuntu 11.04 and Windows XP SP3.
