Package: libqt4-opengl Version: 4:4.7.3-2 Severity: serious Hello, libQtOpenGL.so.4 (libqt4-opengl package) broke ABI in 4:4.7.3-2 on armel [1]. This was caused by switch to OpenGL ES. In particular: - _ZN10QGLContext12chooseVisualEv@Base 4:4.7.2 +#MISSING: 4:4.7.3-4# _ZN10QGLContext12chooseVisualEv@Base 4:4.7.2 QGLContext::chooseVisual() is a _virtual_ protected method in a public class. Changes to vtable mean that potentially old QGLContext using code might just crash without any notice. OpenGL ES switch must be handled by renaming the package on armel and doing a proper transition. The only option I see now is revert of the switch and binNMUs of all libqt4-opengl rdepends which were rebuilt between 4:4.7.3-2 (2011-06-17) and by the time revert is uploaded.
