core on RTF import

[John Levon]

Hi Abi people, 0.7.9 (Linux GTK build) cores on the RTF
file found at :

https://sourceforge.net/project/filelist.php?group_id=4387

I haven't included a backtrace here as it happened at home
and you can easily check it yourselves

apologies if this is fixed in CVS !

keep up the good work
john
