Hello, Sorry that it took so long for the bug to be processed.
In the initial submission, there was not much information which could help to reproduce it or give any substantial hint. I don't know if that ancient version of aptitude used an .old file, probably it did already, and at the time the state of the system could at least be restored to the old one: $ ls -1 /var/lib/aptitude/* /var/lib/aptitude/pkgstates /var/lib/aptitude/pkgstates.old Other than that, the problem might have been a memory corruption in aptitude (or one of the libraries that it uses), causing the file to be corrupted when written to file. Or having any other problem, the writing of the pkgstates file being done only partially, and thus also become corrupted. Or a disk failure, faulty kernel driver, etc... difficult to know by now. So if this bug report isn't more useful in the current state, if we don't get more info about it it's probably better to just close it.
