Package: marco Version: 1.10.2-1 Hi,
First, please note that I use a Sid box which I update regularly (once or twice a day) but I rarely log out, so this bug appeared tonight on my box but it may be caused by an earlier update of marco, or a lib it (or plank) uses. Since both MATE and Plank have several maintainers in common I hope you'll be able to investigate further. If Plank is set to hide (either dodge, auto-hide or intellihide, the result is the same) and one icon regroups several windows from the same application, right-clicking on the icon and trying to restore a single window makes marco crash (and restart). When it happens, .xsession-errors shows a message like this: Anomalie dans le gestionnaire de fenêtres : Unexpected X error: BadWindow (invalid Window parameter) serial 67499 error_code 3 request_code 12 minor_code 0) (The french part roughly means "anomaly in the window manager"). This doesn't happen when I left-click on the icon (which restores all of the application's windows), so it may be linked to the window selection pop-up; and it doesn't happen if Plank isn't set to auto-hide, either. Also, a hunch tells me that it may be related to a long-crawling bug in Gtk3 because for quite some time now it has problems with things that (un)hide, like the top toolbar in VNC clients such as Remmina, Vinagre or virt-viewer; see for example #771784 or #789763 on Debian BTS, #1312780 in Launchpad, #1021838 on RedHat BTS or #692860 on Gnome BTS (no crash involved in these bugs, but the toolbar doesn't appear at all, or doesn't behave properly, which I witnessed personally in all those clients since I use VNC quite often on several systems), but please note that this is only a hunch from a totally non-dev admin.
