Package: aptitude Version: 0.7.8-1 Hi,
aptitude segfaults under the following circumstances: 1. Log in as root on a Linux virtual console, i.e. after pressing Ctrl-Alt-F1. 2. Start aptitude in TUI mode, i.e. without any options or parameters. 3. Press Ctrl-Z to suspend aptitude. 4. Enter "fg" on the commandline and press Enter to bring aptitude back to the foreground. 5. Segfault. This does not happen, if * if tried inside an xterm * if just TERM is set to "linux", but the terminal is no virtual linux console, i.e. "env TERM=linux aptitude" does not exhibit the issue. Unfortunately I was not able to reproduce the issue under gdb directly. But this is the backtrace I got out of the core dump: Reading symbols from /usr/bin/aptitude-curses...Reading symbols from /usr/lib/debug/.build-id/17/b0aa382e98a7c74b766fe389e4e2c494dd8cce.debug...done. done. warning: core file may not match specified executable file.
