Well, that will not be helpful!

Program received signal SIGSEGV, Segmentation fault.
0x08075f46 in malloc at plt ()
Missing separate debuginfos, use: debuginfo-install skype-4.1.0.20-fc16.i586
(gdb) bt
#0  0x08075f46 in malloc at plt ()
#1  0xf4759708 in ?? () from /usr/lib/nvidia/libGL.so.1
Backtrace stopped: previous frame inner to this frame (corrupt stack?)

That backtrace is limited to two proprietary guys: Spype and the NVidia binary 
driver!

renoir ~ $ rpm -q skype qtwebkit.i686 xorg-x11-drv-nvidia-libs.i686
skype-4.1.0.20-fc16.i586
qtwebkit-2.3.0-1.fc17.i686
xorg-x11-drv-nvidia-libs-304.64-3.fc17.i686


I have verified that the following does not segfault:
  LD_PRELOAD=/lib/libGL.so /usr/bin/skype

As I said, downgrading to qtwebkit-2.2.2-5.fc17.i686 also fixes the issue. 
Let's wait for the developers of those proprietary binaries to solve the 
problem. Anyway, I have several workarounds (downgrading or preloading the 
non-nvidia libGL).
