No, the certificates/crypt/config.xml file causes a segfault in both i686 and x86_64 versions of Fedora 12.
Instead of deleting or moving the crypt directory, you can use the aucm utility (it's installed with adobe air) to mark all the certificates as trusted (or use "default" in place of "true" if you like)
Code:
for c in /etc/opt/Adobe/certificates/crypt/*.0; do aucm -n $(basename $c) -t true; done
I'm not sure why this fixes the SIGSEGV, or why it is necessary in F12, but it works.
Similarly, if you delete the certificates with the -d option, and then add them all back with the -a option it also fixes the segfault, so maybe there's some subtle parsing issue with the config.xml file.
