software-center crashed with TransactionFailed in _run_transaction()

[Domen Vrankar]

I upgraded from ubuntu 12.4 (with all updates) to ubuntu 12.10 beta 1.
Before I had mysql-workbench-gpl package installed (I don't know whether I installed it through ubuntu software center or from mysql web page).
I opended MySql workbench and closed it 15 minutes later without using it. When I closed it it created a crush report and notified me that this is not a supported ubuntu package so the report won't be sent (this is why I'm describing this part - I don't know if this realy wasn't an ubuntu package in 12.04 or if this is another bug).

I had ubuntu software center opened and listed all the software that contains word workbench.
I couldn't install MySQL workbench package from ubuntu software center (error message popped up during instalation) so I deleted the previous package with: sudo apt-get remove mysql-workbench-gpl
I started installing MySQL Workbench and noticed that mysql-workbench-gpl is listed below so I clicked Remove button (this was already after I deleted the package with the command above). At this point this crash report popped up.
All this time I haven't closed the ubuntu software center.

After all of this the package mysql-workbench-gpl is still present in ubuntu software center under tehnical items but there is no install or remove button present.

[Michael Vogt (mvo)]

This is probably due to the new "aptdaemon" based size calculation code.

[Gary Lasker (gary-lasker)]

Added aptdaemon task per mvo's comment #2.

Status changed to 'Confirmed' because the bug affects multiple users.
