Public bug reported:
Binary package hint: update-manager
Hello. This is about the latest (and older) update-manager on Gutsy.
I have the update-manager window opened with the "Changes" tab selected
and expanded, so it shows the changes for every package to be updated.
Imagine there are three packages in the updates list, A, B and C. If A
is selected, its changes are displayed correctly below it. If I press
down arrow on the keyboard, the B package is selected, its changes
should be looked-up and displayed. The same for C.
This works OK normally, but:
(We're back with A selected.) I click down, B gets selected. The Changes
tab briefly displays "Downloading the list of changes" or something
similar. This is the trick: If I press down again _before_ the changes
for B are displayed (this happens often for me, but it might depend on
your connection), then the bug happens.
Usually the changes for C are displayed (not sure why it's quicker than
B), then I get a warning in the console, then the changes for B are
displayed, although C is still selected. I can get the changes for C by
going back to B and then returning to C.
Here's an example for this happening three times in a row:
/usr/lib/python2.5/site-packages/UpdateManager/UpdateManager.py:584: Warning:
/build/buildd/glib2.0-2.13.7/gobject/gsignal.c:1741: instance `0x875ece0' has
no handler with id `362'
button.disconnect(id);

no handler with id `377'
button.disconnect(id);
I suppose a callback waiting for the download of the changes forgets to
check if it should still display them.
