Hi,

This problem is caused by fltk. There is a bug in fl_draw_pixmap in
version 1.1.4 on amd64. FYI hdspconf is affected also (it should
segfault also if you switch to the About tab, as it uses
fl_draw_pixmap). I filed a gentoo bug report but got no answer yet (and
probably won't, that was a month ago...). You need to install a more
recent fltk version (1.1.6 is the current). I attached an ebuild for it.
You'll have to download the .bz2 sources from fltk.org and put them in
your distfiles directory. Then run "ebuild /path/to/fltk-1.1.6.ebuild
digest" and emerge.
