aptitude-dbgsym and libc6-dbgsym was already installed. I've installed libcwidget*-dbg, libapt*-dbg, libsigc++-*-dbgsym and libboost-dbg today. But now I can't reproduce the segfault anymore, at least on amd64. And the backtrace from the existing segfaults hasn't changed much -- if at all -- since then: (gdb) bt #0 0x00007fe2861e5973 in ??
