Ok, so I used a downloaded copy of the i686 firefox for my example of the issue I am seeing here. I've attached two screenshots, one is what you see in a default Kubuntu amd64 system and the other is after I installed the 32-bit version of the libqtcurve.so gtk engine.
Firefox emits the same Gtk-WARNING as Pandora. Gtk-WARNING **: /usr/lib/gtk-2.0/2.10.0/engines/libqtcurve.so: wrong ELF class: ELFCLASS64 ia32-libs installs base gtk engines, 32-bit versions, but it doesn't include qtcurve, which I would expect. I do not know how to solve the problem, but the solution is to include a 32-bit version of libqtcurve.so for 64-bit Kubuntu systems. Putting the engine in ia32-libs doesn't seem like the correct location as that is used by Ubuntu as well whereas this change is specific to Kubuntu. I am willing to do the work, just not sure what that work is. Is there a Kubuntu specific package that is installed for 32-bit compatibility on 64-bit systems? ** Attachment added: "Default look of 32-bit Firefox on 64-bit Kubuntu" http://launchpadlibrarian.net/47905815/default_look_of_i686_firefox.png -- On a 64-bit install, 32-bit apps will not be skinned by this engine https://bugs.launchpad.net/bugs/574476 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to gtk2-engines-qtcurve in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
