Ok, sorry about that :*), I'm not that used to gdb yet. After the handle and
continuing, when I change to a VT I get the following gdb log: 


Program received signal SIGSEGV, Segmentation fault.

Continuing.

The first sigsegv seems inside glibc, as I have to continue to get the xorg
one. Unfortunately I don't have glibc with USE=debug; if necesary I will
recompile it but I foresee major breakage, even not changing versions if I do
that. Just in case, glibc is 2.6.1 with useflags (glibc-omitfp nls -debug
-glibc-compat20 -hardened -multilib -profile -selinux). 


As I saw something about XAA I tried with EXA instead, but the backtrace is
pretty much the same, just without the XAALeaveVT line:
