Hi Erwan,

can you reproduce the bug by running dspam manually? If yes, could you install 
the dspam-dbg package and get a backtrace?

To get the backtrace with gdb you must first run dspam inside gdb:

"gdb --args dspam <arguments>" where <argument> is to be replaced by the 
arguments you give to dspam usually

Then, enter "run" to launch the program and when the bug happens you need to 
enter "bt" which will display the stacktrace. This information would be 
helpful to debug the problem.

Best regards,

Thomas Preud'homme
