This has happened to me, too. But today it worked for me.

Hard to say whether this is a true bug.
Google libmurrine ... "Murrine GTK2 cairo theme".
Maybe one can choose a different theme and avoid the library
in order to see whether xfburn still crashes.

Well, this seems to be the immediate cause of the SIGSEGV.

Like with the i386-Ubuntu occasion half a year ago, we see no
accusations against the xfburn code before this happens.
The normal ways how an application can spoil a library are
supposed to get detected by valgrind.

Do i get it right that this is 32 bit code ?
Something seems to be wrong with xfburn and XFCE+GTK on 32 bit
But what ? And why rather rarely ? Is everybody else on 64 bit ?

Have a nice day :)
