(gdb) Ok, so relevant:

what I see in src/process-window.c
static void
xtm_process_window_hide (GtkWidget *widget)
{
gint winx, winy;
g_return_if_fail (GTK_IS_WIDGET (widget));
if (!GTK_IS_WIDGET (XTM_PROCESS_WINDOW (widget)->window))
return;
gtk_window_get_position (GTK_WINDOW (XTM_PROCESS_WINDOW (widget)->window), &winx, &winy);

gtk_window_move (GTK_WINDOW (XTM_PROCESS_WINDOW (widget)->window), winx, winy);
GTK_WIDGET_CLASS (xtm_process_window_parent_class)->hide(widget);
}
tested on ArchLinux as xfce4-taskmanager-git 1.2.0.r94.gb89ba57e-1 also happens with extra/xfce4-taskmanager 1.2.0-1
I have no idea how to fix this, please advise. Cheers!
