Comment 2 for bug 1322763

note: .testrepository/times.dbm needs to be deleted if created by an incomplete test run with < 0.0.19.

what i comprehend from the code change (commit 87e0de0) and validated through testing...

the change directly affects the writing of the database and indirectly the running of the tests, so if a database was written with < 0.0.19 during an interrupted test run, then the problem will still exhibit itself even after an upgrade as the "invalid" data will still be read from the database by 0.0.19. (not to be misinterpreted as me suggesting testrepository should start versioning and upgrading its database.)
