           Summary: "Bad" UAT entry can't be removed via the Wireshark GUI

It appears that a UAT entry with an error (at least for DLT_USER) can't be
removed via the UAT GUI.

Example:

1. Create a User DLT UAT entry specifying a protocol "xxx" (a plugin).
   Exit Wireshark.

2. Remove the "xxx" plugin.

3. Restart Wireshark;

   There will be a pop-up about a DLT load error: "can't find protocol".

4. So: go to DLT_USER pref to remove the table entry.

   Surprise: there's no entry (because there was an error loading it ?).

Obviously this is a pathological case. Are other types of UAT field validations
handled in a similar manner (i.e., don't load the entry if the validation
fails) ?

If so, I could imagine there's other situations wherein a UAT entry becomes
invalid after it's created and thus needs to be edited/removed.

Does Wireshark need to be able to handle this type of situation ?
