I can confirm this bug. I believe it is a gtk filechooser bug and has nothing to do with firefox. I can reproduce this behaviour in gedit and gimp. This is a really annoying bug, as we're talking about 25s that it takes to load the file chooser on my workstation (in every Gnome application!).
I attached a valgrind log of gedit when opening a file. ** Attachment added: "valgrind.log" http://launchpadlibrarian.net/26059534/valgrind.log -- Uploading Files to Firefox Painfully Slow https://bugs.launchpad.net/bugs/364729 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
