I have these sets variables:
sets "Admin" "Cacatoes, ProbablySomeOtherGuys"
sets "Email" "email@example.com" # faked when pasted
sets "Website" "http://openarena.tuxfamily.org"
sets "Location" "France"
And maps were started with such lines:
set d1 "g_instantgib 1; g_gametype 4; map ps9ctf; set nextmap vstr d2"
I removed the elimination map I had the problem on since, but here was the line:
set d2 "g_instantgib 0; g_gametype 9; map ctf_inyard; set nextmap vstr d3"
I suppose using Elimination in particular adds a few cvars being added to the whole stuff. Only tried with that map (ctf_inyard) and oa_ctf4ish, I don't remember on which one I had the crash, I think the latter but not sure at all.
