#91 FVWM2 doesn't show anymore in FvwmButtons

[Anonymous]

Since the update from 4.1 of fbpanel I don't see it anymore in my FvwmButtons.

I have only the trayer in use:
foo@bar:~$ cat /home/foo/.config/fbpanel/default
Global {
edge = bottom
allign = left
margin = 0
widthtype = pixel
width = 200
heighttype = pixel
height = 32
roundcorners = false
Transparent = true
TintColor = 0xFF00FFFF
Alpha = 255
}

Plugin {
type = tray
}
in FVWM I add fbpanel as following:
*FvwmButtons(3x1,Swallow "fbpanel" "Exec /usr/bin/fbpanel")
This worked for the last years. Now it seems that fbpanel doesn't allow to be swallowed anymore. I am not sure if this is a fbpanel or FVWM2 bug.
