Bug description:
Software Center 5.2.1, Ubuntu 10.04
When testing the fix for a similar crash in bug 920196, I found that
even with that fix I was able to cause a (different) crash by
repeatedly clicking the "All Software" button while Software Center is
starting up.
The stacktrace is shown below.
TEST CASE:
1. open stock software-center
2. click on the "All Software" button very quickly while the main page is
still loading
3. verify that there is a traceback (note that this does not happen always,
just most of the time)
4. use the fixed version from -proposed
5. verify that (2) no longer produces the following (or any) traceback
