1 Title: Fix exception in WATO host editor on custom tag without topic
8 When you've defined a host tag group in WATO that has no topic,
9 then the host edit dialog would be interrupted with an exception.
10 A simple workaround to this is to alwasy define a topic.
12 The problem has now been fixed. It had shortly been introduced by fixing a
13 problem appearing when you used a slash in the name of a tag group.
