Have you overwritten your Qt 4 installation or tried to install another Qt version from source? This is what this bug looks like to me. What happens if you try reinstalling the libqt4-svg package in Synaptic?

Thanks!

I reinstalled the libqt4-svg package in Synaptic and reinstalled mixx: same result:

mixxx: symbol lookup error: /usr/lib/libQtSvg.so.4: undefined symbol: _ZN15QGraphicsObject16staticMetaObjectE

[Frank Neirynck (redactie-stadsomroep)]

All previous installations were done from Ubuntu Softwarecenter. No other sources were used

I have exactly the same error message when I try to start k3b:
jringoot@legolas:~$ k3b

jringoot@legolas:~$ k3b
k3b: symbol lookup error: /usr/lib/libQtSvg.so.4: undefined symbol: _ZN15QGraphicsObject16staticMetaObjectE

no error in the gui, the above error is generated from a command prompt:

I have it since I upgraded to ubuntu10.10, when I try to start k3b

I also tried reinstalling libQtSvg.so.4, but this gave no resolution

[Alessio Treglia (quadrispro)]

Please try to reproduce this with the new release available in Maverick.

[Joost Ringoot (joost)]

Hi Alessio,

Thanks for the response.

How do I quickly prove that I have the new release as available in maverick?

root@legolas:~# uname -a
Linux legolas 2.6.35-22-generic #34-Ubuntu SMP Sun Oct 10 09:24:00 UTC 2010 i686 GNU/Linux
root@legolas:~#

I just did a "apt-get update; apt-get upgrade" it gave no errors

I noticed that there a lot more programs affected by Qt 4 broken:

jringoot@legolas:~$ k3b

suggestions are welcome

I explain why it is a duplicate bug:
It got broken by installing the be id reader software: needed to submit my taxes (Hey I am from Belgium? yes.)

I did the following:
mkdir -p Desktop/usr/local/lib/beidqt/mkdir -p Desktop/usr/local/lib/beidqt/
mv /usr/local/lib/beidqt/libQtGui.so.4 Desktop/usr/local/lib/beidqt/
mv /usr/local/lib/beidqt/libQtCore.so.4 Desktop/usr/local/lib/beidqt/

And amarok, k3b, kate, vlc,... all those QT4 depending apps work again.

Thanks all
Same here with the Belgian ID reader...

Belgian Gov really needs help ;-)

Furthermore, the application beid is not broken after doing this, (I am sure those files are some old crap they ripped somewhere)
And it are actually links to /usr/local/lib/beidqt/libQtCore.so and /usr/local/lib/beidqt/libQtGui.so
