Comment 3 for bug 141178

ok, i found the culprit. The Clearlooks engine crashes because of my ~.gtkrc-2.0 code (specifically, the bits about the tooltips):

style "my-narrow-tree" { GtkTreeView::expander_size = 0 }
widget "*gaim_gtkblist_treeview" style "my-narrow-tree"

style "smaller-text" {
font_name = "Sans 7"
}

style "clearlooks-tooltips" = "clearlooks-default"
 {
    xthickness = 4
    ythickness = 4
    bg[NORMAL] = "#FFFF66"
  }

widget_class "*Toolbar*" style "smaller-text"
widget_class "*Statusbar*" style "smaller-text"
widget "gtk-tooltips" style "clearlooks-tooltips"

This piece of code WORKS with all other theme engines, but it crashes with the LATEST clearlooks (it worked fine until very recently). I call this a new clearlooks engine bug.
