We like to work on it. But so far I haven't seen someone provide the  
necessary debugging (maybe jhb got something and I didn't got a CC).  
We need a ktrace of it.

Most of the time a wrapper script is called when running a linux  
program. This is at least true for skype and acroread. So there are  
two possibilities:
  - run "ktrace -i" and hope the mixed information (FreeBSD sh and  
linux binary) can be decoded
  - modify the wrapper script to run ktrace on the real linux binary

To process the ktrace.out file, you need to use the linux_kdump  
program. I made a package (32bit) available at  
http://www.leidinger/net/FreeBSD/

Most interesting is the information which syscall is called before the  
coredump, but the entire log would be ok too (please don't send it to  
the list if it is large). So if anyone is able to provide this  
information: we prefer to get it even from several people instead of  
not at all.

Bye,
Alexander.
