thunderbird and gtk-qt4-engine problem

[Chopstick]

Hi,
I'm rather new to kubuntu (running 8.10); previously I was running windows vista but I was using thunderbird and lightning for email and calendar.
The version of thunderbird supported by the repositories appears to be an older one; unfortunately the calendar data is not backwards compatible and I had to install thunderbird manually. That actually works fine, except that it looks like an old windows 98 application... nothing of the new and fancy look... (firefox does not have this problem)
I get the following error when I start thunderbird from the konsole:

/$ /opt/thunderbird/thunderbird

(thunderbird-bin:31407): Gtk-WARNING **: /usr/lib/gtk-2.0/2.10.0/engines/libqt4engine.so: wrong ELF class: ELFCLASS64

(thunderbird-bin:31407): Gtk-WARNING **: /usr/lib/gtk-2.0/2.10.0/engines/libqt4engine.so: wrong ELF class: ELFCLASS64

Does anyone know what this is? I tried (re-)installing some gtk and qt4 libs but that didn't help at all (mostly they were already present)

So all the functionality of thunderbird (2.0.0.19) is there but it simply looks "old"... (it looked much better in windows...)

Chopstick,

Instead of installing Thunderbird manually, I would install thunderbird from the repository, install the package libstdc++5 and then install Lightning 0.9 from the Thunderbird add-on page. If you had problems with Lightning in the repo's Thunderbird before, it was probably from not having libstdc++5 installed.

Then, I would recommend the new Oxygen-Molecule theme on KDE-Look.org. It's designed to make GTK+ apps blend in with the default Oxygen style of KDE 4.2. Certain widgets in Thunderbird will still have an old style, but that's Mozilla's fault, and there isn't anything we can do about it as far as I know.
