System-wide profiles don't seem to find debug information since Fedora 15

[Clemens Eisserer]

Hi again,

Since it indeed seems to be a regression, I filed a bug-report about this:
https://bugzilla.redhat.com/show_bug.cgi?id=746823

Hopefully when its fixed, I can continue playing with firefox's
performance improvements ...

Thanks, Clemens
