I can reproduce this on an i386 system with the same version of fontforge. :( When trying to get a backtrace with fontforge-dbg 0.0.20110222-6 installed, i get the following error message (twice) from gdb: warning: the debug information found in "/usr/lib/debug//usr/bin/fontforge" does not match "/usr/bin/fontforge" (CRC mismatch). Pressing ahead anyway, i can trigger the segfault, and i get this (partially-mangled) backtrace: xb7c7ec4c in CVLayer (cv=0x86a3858) at cvundoes.c:552 552 cvundoes.c: No such file or directory. in cvundoes.c (gdb) bt #0 0xb7c7ec4c in CVLayer (cv=0x86a3858) at cvundoes.c:552 #1 0x0808faf0 in ??
