Duplicating workspace list on click

[TripsJ]

I added a perspective besides main. If i click on the modebar indicator to switch perspectives the whole list gets duplicated and appended to the perspective list. switch-perspective bound to a key seems to work fine.

I added a screenshot to illustrate. Any idea where this behaviourt might come from ?

It’s probably the code in persp-update-modestring. It looks like you have a fairly sophisticated modeline setup, so it’s hard to tell where Perspective’s modeline updating code conflicts with it.

In other words, I need a simple reproducible example.
