GuitarPro6 segmentation fault Ubuntu 64 bits

mv ~/.ArobasMusic ~/.ArobasMusicbkp

If this does not work (Ubuntu 11.04), and the error is :

GdkPixbuf-CRITICAL **: gdk_pixbuf_get_height: assertion `GDK_IS_PIXBUF (pixbuf)' failed
Segmentation fault

then downgrade the ia32-libs package :
(from http://getsatisfaction.guitar-pro.com/arobas_music/topics/after_ubuntu_11_04_upgrade_i_cant_open_gp6)

It seems a bug in the latest ia32-libs causes some trouble to applications that uses 32bit libraries (GP6 use 32 bit libraries too).

A workaround exists, simply downgrade the ia32-libs package.

Follow these guidelines to downgrade ia32:
- download the package from this page http://packages.ubuntu.com/maverick/amd64/ia32-libs/download
- execute this command line: sudo dpkg --force-downgrade -i ia32-libs_20090808ubuntu9.1_amd64.deb

# modify L only
L.append(obj)
