If you can.... Run your Lazarus in gdb.
    gdb path/to/lazarus

and then in gdb hit r and return.

I know you want to get away from more crashes. And this will mean at 
least one more of them.

It is highly likely that gdb will report some sort of sigsegv or the 
like. And then allow for a backtrace to be made.
Of course that assumes, that your lazarus is compiled with debug info.

You can also look into your home dir (or where you start lazarus from), 
or maybe the lazarus dir, or ~/.lazarus.
Maybe there is a lazarus.core file. Then you already have what you need. 
Or well, only if it has debug info.
    gdb path/to/lazarus path/to/lazarus.core
