Thanks! With that config file, I can reproduce the crash even with the
latest version from the Mercurial repo. Seems like the problem is when
you specify an FPU together with the GEMDOS hard disk. I was able to
reproduce it with this minimal config file, too:

[HardDisk]
bUseHardDiskDirectory = TRUE
szHardDiskDirectory = /tmp/hatari/gemdos.drv

[ROM]
szTosImageFileName = /tmp/hatari/etos512k.img

[System]
n_FPUType = 68882

The "n_FPUType = 68882" seems to trigger a re-initialization of the CPU
tables (even though it likely should not do that) as soon as you press
the OK button in the GUI. I guess that somehow kills the special
GEMDOS HD opcodes of Hatari, so that you finally run into a crash.
Unfortunately, I currently don't have much time for further debugging
(for the next 1.5 weeks) ... so either somebody else needs to have a
closer look or this has to wait a little bit.
