Firefox install-problem

Fri Aug 3 13:20:54 UTC 2012

Hi,

Firefox, built from .srpm from F17-updates repository, fails to install:
This is the error-message which shows up:

"Unpacking of archive failed on file /usr/lib64/firefox/firefox;501bceec: cpio: Digest mismatch"

The package is original Fedora and not altered in any way. Extracted
it, ran "rpmbuild -bb" on the .spec file, and the built was ok.

Does anybody know what's the cause or where to look?
