Comment 2 for bug 145360

In order to make a backtrace I looked at https://wiki.ubuntu.com/Backtrace, but I cannot work out how to start compiz under gdb. I went into the Appearance setting and changed 'Visual Effects' to 'None' and then tried these two ideas, neither of which worked:

duncan@duncan-laptop:~$ gdb compiz-core 2>&1 | tee gdb-compiz-core.txt

Tell me what to do and I'll try it.
