Variables not available

[Rod Butcher <rbutcher hyenainternet com>]

I get very many examples of variable not available (e.g. evolution 
example below) when I try to get stack traces using either "thread apply 
all bt" or just "bt". Yet I understand that if I build from cvs it 
should build in debugging info - I understand -g is most important, 
correct ? I tried manually setting -g and still get mostly "not 
available". Am I doing something wrong or is this inevitable and if so why ?

#4  0xb6b48e96 in signal_emit_unlocked_R (node=Variable "node" is not 
available.
) at gsignal.c:2438

thanks
Rod
