that's a big crashlog, never saw it like that before. did you installed Quake3 Arena with app manager and moved the patched pk3 files to baseq3 map? you don't need to and better not copy any config. just copy the pk3 files to home/user/.q3a/baseq3, only the autoexec.cfg must be edited if wanted and it works when not edited when fresh installed Quake 3
