I had other segfaults, in case that info can be usefull... here's the summary
....
I'm running PCManFm in Gdb in my lxsession autostart file, so every time it
crashes,
I can get a backtrace, that happens in the dir tree model, places model, and
folder
model when removing a row.
I only found this in desktop.c, I don't know if that can make it crash :
void on_row_deleted(GtkTreeModel* mod, GtkTreePath* tp, FmDesktop* desktop)
{
GList* l;
int i = 0, idx = gtk_tree_path_get_indices(tp)[0];
for(l=desktop->items;l;l=l->next, ++i)
{
FmDesktopItem* item = (FmDesktopItem*)l->data;
if(i == idx)
{
desktop_item_free(item);
if(desktop->focus == item)
it's strange here to free the item and then using it ??
{
if(l->next)
desktop->focus = (FmDesktopItem*)l->next->data;
else if(l->prev)
desktop->focus = (FmDesktopItem*)l->prev->data;
else
desktop->focus = NULL;
}
if(desktop->drop_hilight == item)
desktop->drop_hilight = NULL;
if(desktop->hover_item == item)
desktop->hover_item = NULL;
desktop->items = g_list_delete_link(desktop->items, l);
break;
}
}
queue_layout_items(desktop);
}
------------------------------------------------------------------------------------------------------------------------
Delete a directory on the desktop, file manager closed, doesn't happen every
time,
just somtimes...
