Hello,

When using the latest version of the code from "trunk", revision 2147 as of the
time I'm writing this, I get a segmentation fault when playing Q3DM12 single
player and pressing the "restart" button once the match finishes.

This happens on Slackware Linux -current as of today, x86_64 version. I can
provide more information on request. I'll try to attach a core file I have, but
it's 32 MB compressed. The backtrace looks like this:
