Comment # 11 on bug 1188687 from Episteme PROMENEUR

yes it was only a hypothesis.

but it is true.

with kde network setting I set in "general setup" tab the parameter "connect
automatically with priority" to "1" instead of "0"

then no more problem when using "connect" button.

but we must consider this default setting as bad setting. When we create a
bridge with the assistant, it must set all the values to good values. It's too
techie for a user. It is too techie for a user to know the master must not
automatically start, and the slave must start automatically with priority 1.

this must be fixed.
