Hi Martin,

    crashing immediately on startup could be to do with the UUIDPlugin and
libuuid.  Try removing coglinux/lib/squeak/3.9-7/UUIDPlugin and see if it
makes a difference.  If it does I believe the fix is to ensure that there's
a 32-bit libuuid.so.1 installed.  e.g.

[eliot at mcqfes bld]$ ldd coglinux/lib/squeak/3.9-7/UUIDPlugin
        linux-gate.so.1 =>  (0x00e2e000)
        libuuid.so.1 => /lib/libuuid.so.1 (0x0067e000)
        libc.so.6 => /lib/libc.so.6 (0x008d6000)
        /lib/ld-linux.so.2 (0x0045a000)
[eliot at mcqfes bld]$ file /lib/libuuid.so.1
/lib/libuuid.so.1: symbolic link to `libuuid.so.1.2'
[eliot at mcqfes bld]$ file /lib/libuuid.so.1.2
/lib/libuuid.so.1.2: ELF 32-bit LSB shared object, Intel 80386, version 1
(SYSV), stripped

Search the Squeak, vm-dev and Pharo archives for info on how to install a
32-bit version.  I think it was mentioned within the last month.

If your problem is nothing to do with libuuid then I need info like exact OS
version, what directories you've installed things in and a gdb backtrace for
the crash.
