I have recently inherited a cent-os machine with a non functioning yum after the abrubt departure of my new employers previous admin. I have a few ideas but thought I would post the symptoms without muddying the water with my suppositions. If I start python from the command line and do an import on any module I can think of (os, sys, math) it works fine. If I try "import yum" python segfaults instantly. If I start yum from the command line directly, of course it segafaults straight away. Does anyone have any further testing I can do, some method to turn on debug mode if you will? If anyone wants the output of strace -o, or has any ideas at all please feel free to speak up. My most sincere thanks in advance, -James
