you have right mike > Since I tend to do > upgrades wholesale, I only find the ones where the breakage is exposed > at the source level, so the last one I recall is when libgtkhtml > changed the underlying print engine, breaking anything that depended > on it for printing, like gnucash. > I want to share one thing: I restarted my box right now (since I upgraded my box I haven't restarted) and I saw one interesting thing: - before upgrade GIMP was able to load PNG files - after upgrade GIMP can't load PNG files - when I did the symbolic link GIMP was able to load PNG files ONCE AGAIN - I delete the symbolic link, then restarted my box AAANNNDDDD GIMP is able to load PNG files ONCE AGAIN there is happening something that I don't know yet???? somebody knows???? _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
