Bug#741685: libapt-*: 0.9.16 regression: files are closed twice
Package: libapt-pkg4.12
Version: 0.9.16
Severity: serious
Probably following the recent changes to the FileFd compressor
handling, some files now get closed twice. I noticed this while
running the python-apt test suite. It works on 0.9.15 but fails
on 0.9.16 (the backtrace below is most likely wrong, though).
It also occurs only under python3.4. Choosing Python 3.3 or
APT 0.9.15.5 fixes the bug. The same applies to Bug#741682. Maybe
APT is corrupting memory somewhere?
