2017-02-02 10:39 Marcel Partap:

also occurs when I issue `aptitude safe-upgrade` f.e.
similar backtrace:


I believe that this is the same as #849370 and #836567.  There's a patch
attached to the last one, which you can try, and I would be grateful of
any feedback.

In any case, if I get this patch to stable or the new version and this
keeps happening to you when the fix is released, please reopen the bug.


Cheers.
