This error appears only since yesterday's update, i have never seen something like that before. So I guess it is due to one of the packages. I think, it's kernel-headers or Reproducible: Always Steps to Reproduce: Actual Results: Expected Results: mozilla is starting very slowly, brings up a window after several minutes, and updates every view with >20s time difference. In between, it is completely dead.

What i did now: - removed 2.4 kernel headers - re-emerged recent - kernel sources - kernel-2.6 headers - glibc - and the whole previous posted list of packages; The problem was not solved; same behaviour.
Created attachment 38162 [details] kernel config that probably caused the bug, bzipped i using that configuration no more and the problem disappeared
This bug was most probably caused by a weird linux kernel. I used a certain config on 2.6.7 sources , gentoo emerged 2.6.8*-rc2 and 2.6.8*-rc4 sources. I recompiled the kernel with minor changes to the prior config , and got the error. The same happened with the 2.8.1 (dot nothing) kernel on a re-installed gentoo installation. After cleaning the configuration, re-selecting all items and recompiling, my applications ran again well.
