Emacs gives warnings in lubuntu

Question

I am running lubuntu-desktop (quantal quetzal) which I installed after having started with the standard ubuntu install. It all works fine but when I run an application from the command line I get warnings in the terminal. For example emacs gives me

** (emacs:25391): WARNING **: Invalid borders specified for theme pixmap:
    /usr/share/themes/Lubuntu-default/gtk-2.0/images/null.png,
borders don't fit within the image

** (emacs:25391): WARNING **: Invalid borders specified for theme pixmap:
    /usr/share/themes/Lubuntu-default/gtk-2.0/images/scrollbar_vertical.png,
borders don't fit within the image

Is there a way to stop this or is there another way to run emacs that works better for lubuntu-desktop?

Answer 1

This bug report says it is an issue with the theme, not the specific program running: https://bugs.launchpad.net/qbittorrent/+bug/789905

This page says the solution is to run sudo apt-get install lubuntu-.: http://www.richelbilderbeek.nl/CppMiscErrorInvalidBordersSpecifiedForThemePixmap.htm

I ran this solution and the problem went away (I was experiencing the problem when running smplayer [from the ppa] from the command line), but it seems like a bit of an overkill. I'm not sure which specific package was needed to install, since this command installed 17 packages for me:

blubuntu-look blubuntu-session-splashes blubuntu-theme blubuntu-wallpapers chromium-codecs-ffmpeg-extra gtk2-engines-murrine human-theme ldm ldm-lubuntu-theme lubuntu-artwork-10-04 lubuntu-artwork-10-10 lubuntu-artwork-11-04 lubuntu-artwork-11-10 lubuntu-artwork-12-04 lubuntu-elementary-icon-theme lubuntu-restricted-addons lubuntu-restricted-extras

dpkg -S '/usr/share/themes/Lubuntu-default/gtk-2.0/images/null.png' tells me that null.png comes fromthe lubuntu-artwork package, so it is probably that one.

Answer 2

I'm running Kubuntu 12.10 and emacs package from

sudo add-apt-repository ppa:cassou/emacs

and I get

Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `gtk-toolbar-style' of type `GtkToolbarStyle' from rc file value "((GString*) 0x1357640)" of type `GtkToolbarStyle'

on start-up.

Before using the package I used to build emacs myself. And I had no warnings. So I guess the warnings are due to the package. Any way I can't see any problems with emacs even with this warning.
