Tonight I applied all the updates-testing to my FC13A-RC3 system.
The new kernel-PAE-2.6.33-1.fc13.i686 breaks dialup networking, says the kernel is not configured for PPP (I suppose this would also break things like DSL that use PPPOE).
There was a dependency problem with gegl and gimp. gimp 2.6.8-4 says it needs libgegl-0.0 and thus gegl-0.1.2-2 will not install unless forced.
