Program freezes while printing

Hello,

I am trying to print with mrproject 0.9.1 (Debian unstable). When I
click on [Print], whatever printer and settings, the program enters an
endless loop.

So I got the sources and ran with gdb, which tells me that it meets this
instruction:

  mg_gantt_print_do (data=0x828fba8) at mg-gantt-print.c:600
600				tasks_on_this_page = data->tasks_per_page_without_header;

... and tasks_on_this_page is -1184

Is this bug already reported ?  if not, what other info do you need ?

Thanks for any help.
