[Bug 882882] Re: installer crash with ValueError: invalid literal for int() with base 10: ''

[Dmitrijs Ledkovs]

I have a kind-of unit-test reproducer. What happens is that debconf
database is locked and status ends up as empty string.

test_empty (test_ubi_partman.TestCalculateAutopartitioningOptions) ... debconf: DbDriver "configdb": /home/tdlk/canonical/installer/adv-crypto/tests/config.dat is locked by another process: Resource temporarily unavailable
ERROR

Which results in:

======================================================================
ERROR: test_question_dialog (test_gtkui.TestFrontend)

    status = int(status)
ValueError: invalid literal for int() with base 10: ''

My guess is that debconf shouldn't trust 'status' to be a valid value
castable to an int, instead it possibly should check if it's empty and
raise appropriate error.
