I'm going to test it, but just after my bug report, I saw that libapr0
wasn't maching apache2* version, this was the sarge version, so I
installed the sid version and since, I have no segfault, but an apache
process is eating all the cpu and apache log reports:

strace on this process doesn't show anything

I also changed my conf to put MaxRequestsPerChild to 10 instead of 0,
expecting to have less segfaults.



So now I just installed your packages (2.0.54-4) with the original
MaxRequestsPerChild of 0, waiting...
