[galib] not enough memory for evolution?

Hi Annelie

in my opinion it is very unlikely that the program 
crashes because the evolution process needs too much
memory, since that would normally just cause a
of the execution due to swapping between RAM and
hard-disk cache memory.
I would suggest you try to run your application under
a debugger (gdb for instance) and see what happens,
it is otherwise very hard for you to guess what
causes the crash. Also, if your program generates
a core dump before crashing, feed it to gdb:

> gdb -c core path_to_your_executable

it might directly tell you the line where it had
