i've just written to the fontforge-devel list, cc'ing this bug report, and marked this bug as forwarded to http://sourceforge.net/mailarchive/message.php?msg_id=28696933 > So, really, help woul dbe appreciated. i'm also not very clear how i should go about this. I'm particularly concerned, though, because of the weird gdb error messages, which i have no idea how to interpret or workaround. I've tried a rebuild of fontforge from source on a sid i386 system, and my self-generated packages give the same gdb error (and show the same crashing behavior, of course). here's a bit more detail i managed to coax out of the debugger, though: Program received signal SIGSEGV, Segmentation fault. 0xb7c85c4c in CVLayer (cv=0x8667c60) at cvundoes.c:552 552 return( cv->layerheads[cv->drawmode]-cv->sc->layers ); (gdb) bt #0 0xb7c85c4c in CVLayer (cv=0x8667c60) at cvundoes.c:552 #1 0x0808fb00 in ??
