As I tried to say before, the problem appeared with latest 0.8.3, and downgrading did not help. Here's the same backtrace from 0.8.3-1: > Thread 1 "aptitude" received signal SIGABRT, Aborted. > 0xf7727d09 in __kernel_vsyscall () > @@gdb> bt > @gdb> #0 0xf7727d09 in __kernel_vsyscall () > #1 0xf6cc5c19 in __GI_raise (sig=6) at ../sysdeps/unix/sysv/linux/raise.c:54 > #2 0xf6cc7117 in __GI_abort () at abort.c:89 > #3 0x5679d309 in subsumes (d2=..., d1=...) at > ../../../../src/generic/apt/apt.cc:1182 > #4 or_group_subsumes (d1=..., d2=..., cache=<optimized out>) at > ../../../../src/generic/apt/apt.cc:1205 > #5 0x5679f002 in internal_is_interesting_dep (cache=0x586f1440, d=...) at > ../../../../src/generic/apt/apt.cc:1303 > #6 is_interesting_dep (d=..., cache=0x586f1440) at > ../../../../src/generic/apt/apt.cc:1344 > #7 0x567c2865 in aptitude_resolver_version::dep_iterator::applicable > (dep=..., prv=..., prv_open=false, cache=0x586f1440) at > ../../../../src/generic/apt/aptitude_resolver_universe.cc:283 > #8 0x567bbcda in aptitude_resolver_version::dep_iterator::applicable > (this=0xffccb4f8) at > ../../../../src/generic/apt/aptitude_resolver_universe.cc:302 > #9 0x567bbdb9 in aptitude_resolver_version::dep_iterator::normalize > (this=0xffccb4f8) at > ../../../../src/generic/apt/aptitude_resolver_universe.cc:317 > #10 0x567bd095 in aptitude_resolver_version::dep_iterator::operator++ > (this=0xffccb4f8) at > ../../../../src/generic/apt/aptitude_resolver_universe.cc:529 > #11 0x568ab9b7 in aptitude_universe::dep_iterator::operator++ > (this=<optimized out>) at > ../../../../src/generic/apt/aptitude_resolver_universe.h:1246 > #12 generic_problem_resolver<aptitude_universe>::generic_problem_resolver > (this=<optimized out>, _step_score=<optimized out>, _broken_score=<optimized > out>, _unfixed_soft_score=<optimized out>, infinity=<optimized out>, > _full_solution_score=<optimized out>, _unfixed_soft_cost=..., > _future_horizon=<optimized out>, _initial_state=..., _universe=...) at > ../../../../src/generic/problemresolver/problemresolver.h:3782 > #13 0x5689a73c in aptitude_resolver::aptitude_resolver (this=0x5a171308, > step_score=-10, broken_score=-100, unfixed_soft_score=-200, infinity=1000000, > resolution_score=50, unfixed_soft_cost=..., future_horizon=50, > _cost_settings=..., initial_installations=..., cache=0x586f1440, > _policy=0x5883a050) at ../../../../src/generic/apt/aptitude_resolver.cc:731 > #14 0x56814ac1 in resolver_manager::create_resolver (this=0x5a082cb8) at > ../../../../src/generic/apt/resolver_manager.cc:968 > #15 0x56816da3 in resolver_manager::maybe_create_resolver (this=0x5a082cb8, > consider_policybroken=true) at > ../../../../src/generic/apt/resolver_manager.cc:805 > #16 0x56817718 in resolver_manager::reset_resolver (this=<optimized out>, > consider_policybroken=<optimized out>) at > ../../../../src/generic/apt/resolver_manager.cc:218 > #17 0x566ef2a4 in do_package_run () at ../../src/ui.cc:1817 > #18 0xf748445c in cwidget::widgets::widget::handle_key(cwidget::config::key > const&) () from /usr/lib/i386-linux-gnu/libcwidget.so.3 > #19 0xf7456b88 in > cwidget::widgets::passthrough::handle_key(cwidget::config::key const&) () > from /usr/lib/i386-linux-gnu/libcwidget.so.3 > #20 0xf7488b3b in cwidget::widgets::widget::dispatch_key(cwidget::config::key > const&) () from /usr/lib/i386-linux-gnu/libcwidget.so.3 > #21 0xf743321c in cwidget::widgets::menubar::handle_key(cwidget::config::key > const&) () from /usr/lib/i386-linux-gnu/libcwidget.so.3 > #22 0xf7488b3b in cwidget::widgets::widget::dispatch_key(cwidget::config::key > const&) () from /usr/lib/i386-linux-gnu/libcwidget.so.3 > #23 0xf73fab51 in > cwidget::toplevel::input_thread::get_input_event::dispatch() () from > /usr/lib/i386-linux-gnu/libcwidget.so.3 > #24 0xf73f1bef in cwidget::toplevel::mainloop(int) () from > /usr/lib/i386-linux-gnu/libcwidget.so.3 > #25 0x566ef4ae in ui_main () at ../../src/ui.cc:3134 > #26 0x565f83ab in main (argc=<optimized out>, argv=<optimized out>) at > ../../src/main.cc:1427
