Hello Murilo,

nice to hear that. :-)

Yes, there are quite a bit modules involved.

Take a look into the core dump (set core_dump = yes) with gdb, this should 
give you further informations about the cause of the segmention fault. To get 
a better backtrace install the debug package (debian) or compile with 
debugging enabled. If the error is located in openser, please post the 
backtrace also on the list.

Cheers,

Henning
