It seems this type of segfault happens with various other software too.  I believe fglrx is the proprietary Radeon driver.  Is it a VM, or is it a PC with Radeon graphics, or something else?  Are you getting OpenGL acceleration?  (glxinfo, glxgears)  I wonder when you build Qt yourself, how differently it ends up configured compared to the binary package.
