[Aptitude-devel] Bug#810020: aptitude: sometimes crashes when reading changelogs

[Andreas Cadhalpun]

Package: aptitude
Version: 0.7.5-3
Severity: important

Dear Maintainer,

since upgrading to apt > 1.1 aptitude sometimes crashes, when reading changelogs.
So far it happened four times in the last month.

Backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.

This seems to end somewhere in libapt, so it might very well be a bug of apt.
In that case please reassign this report as appropriate.
On the other hand, this might get fixed, when fixing #797527.

Best regards,
Andreas
