I had similar weird behaviors of applications in F16 (x86_64) after I installed glibc-2.14.90-24.fc16.3. I googled and found (in Bug#651899 in Debian) my problem might be related to glibc-rh552960.patch had been introduced in 2.14.90-24.fc16.x. I locally build glibc-2.14.90-24.fc16.3 without the patch then everything have been working fine for two days. I found the patch has been merged into glibc-2.14.90-25.fc17 tarball.
