Segfault only after first launch of FG, then OK

[Maerchenprinz]

Hi there!

I've noticed something strange after having newly compiled FG (and other "complex" programs too! like RoR e.g.) for several times:

- Only the very first start of the program ends in an immediate segfault
- After that, I start the program again, and everything works fine ever after; no more segfaults, flying flawlessly for hours etc...

Have you noticed that, too? If so, would it be worth mentioning somewhere on the Wiki?
Like, someone experiences a segfault after first launch, then disappointed, re-compiles again with different options, and messes it all up,
though the first try was successful?

OS: Ubuntu 10.04 - 12.04 with shipped compilers
NVIDIA GF 8200GS - 9800GT

Not complaining, just curious!

Ciao,
Adrian
