Jannis? I don't think this is my bug. I do know there are plenty of issues with the file monitoring in XfceMenu...
Is this still valid? xfce-mcs-manager is not part of next Xfce. I've changed the target milestone to xfce-4.6alpha because libxfce4menu wasn't part of the 4.4 series at all.
Yeah, no need to fix this as-is since MCS is gone... tho the underlying bug may still be there.
The underlying issue might indeed be still there but IMHO we should close this bug. xfce-mcs-manager is gone indeed and will never be used in combination with libxfce4menu unless someone messes with the dependencies.
This should be caused by the same issue that caused the crash bug when items are added to/removed from the menu.
