[Aptitude-devel] Bug#794862: crashes randomly in libcwidget.so.3

[Yuri D'Elia]

Package: aptitude
Version: 0.7-1
Severity: important

After the update to 0.7-1, aptitude is very unstable.
I can get segmentations faults just by moving the cursor around.

In most of the crashes, the backtrace seems to be either in cwidget or in sigc,
which is probably a signal that one of the two needs a rebuild due to the new
ABI (I've just seen #794705 but nothing in libsigc++ yet).
