[arch-general] Gtk update messed up thunderbird thread marker triangles??

Guys, It seems one of the latest updates did something to the little triangle thread markers in thunderbird that show when a thread has responses. Now the triangles for collapsed threads look like little squiglies. The downward facing triangles showing expanded threads look OK. Anybody else see this? Does this look like a Gtk issue or an issue with thunderbird? This screenshot shows what I'm seeing: [64k] http://www.3111skyline.com/dl/img/misc/tbird-triangles-arch.jpg -- David C. Rankin, J.D.,P.E.
