Running just "aptitude" shows no error (no command issued except "q").
Running "aptitude changelog" (no furter arguments) returns normally
with no output.
Running "aptitude changelog apt" in a writable directory gives a core
dump.
"gdb --core=core" shows:

While "gdb" is working, "top" shows that it uses first about 80 % CPU, then about 6 %
and 83 % waiting (wa). The disk-light is then continously lit.
After "Thread 2 (Thread 0xb435bb40 (LWP 4317)):" there is no progress.
Therefor I issued the "quit" command.
