gui apt tools (synaptic, update-managert, etc) should warn user of apt-cache corruption instead of silently failing

Binary package hint: apt

Ubuntu feisty, fully updated.

Went to synaptic for some package management. Synaptic hung without giving me some hint of error.

So next...fire up the console...

sudo apt-get update ...OK
sudo ap-get upgrade ...Core dump at 50%

After researching this for a while I used the following solution

sudo rm -v /var/cache/apt/*.bin

Now apt does not core dump, which indicates that there was some kind of cache corruption

Problem solved....But the point here is that a user that is using the GUI tools (synaptic, update-manager, update-notifier) will have no clue as to why his system does not update anymore, does not install packages, does not notify him of new updates, etc.

This is a serious usability bug for a distribution that tries to keep it simple.

Please do not mark this as a duplicate, I know there are other bugs related to apt crashes in launchpad, but they are more focused on command line solutions than on GUI notification of the problem.
