Package: aptitude Version: 0.6.3-3.1 Severity: normal I also see this behavior. I believe it is related to the fact that neither of us have apt-xapian-index installed. Installing that package and letting it build an index fixed the segfault for me.
aptitude currently only recommends apt-xapian-index. It should either depend on the package instead or be fixed such that basic searches won't segfault with apt-xapian-index not installed. -- Package-specific info: aptitude 0.6.3 compiled at Aug 26 2010 19:06:44 Compiler: g++ 4.4.5 20100816 (prerelease) Compiled against: apt version 4.10.0 NCurses version 5.7 libsigc++ version: 2.2.4.2 Ept support enabled.
