As far as I know, you can only have one open capture file. Correct me if
I am wrong.
Both File sets and opening files manually result in all packet dialogs
getting closed after opening a new capture (v1.99.4rc0-34-g6bc138c).
This is the current GTK+ implementation, Qt crashes for the reasons
mentioned in bug 11044.
A split model/view can in theory allow for opening multiple capture
files in separate views, this would need some additional refactoring
though.
