It is quite often the easiest way to get a traceback.  Please ensure that 
debug symbols are available.  The debugger will inform you of this when it 
loads bacula.  If they are not available, then you will need to find the 
debuginfo packages and load them or build Bacula without stripping it as most 
rpm installations do.

If Bacula is properly installed you can "force" it to dump itself by killing 
it with a -15. 

This is discussed in more detail in the manual.
