With Pager 1.0.0 Panel/Pinboard show up as "ROX-Filer" in the window
list. This issue comes up again and again.
I've finally resolved it :)
It was never clear (at least to me) wether this is a window-manager bug
or or a libwnck bug. Turns out it's neither. It's just how libwnck
works. It doesn't do any filtering, but will return a list of all
windows managed by the window-manager. So only override_redirect
windows are omitted.
The attached patch filters out windows of NET_WM_STATE
As that's what they are there for.
