[Bug 1736074] Re: terminal window in update-manager does not resize correctly

[peter swain]

Me, too.
I've seen this before, and fixed it by rolling in a patch someone proposed last time it was seen (about 15.04/15.10?).
Now it's happening again on 17.10, so I suspect the fix, which had later rolled into some python support package, has come unstuck in a more recent revision.
Actually it began affecting this machine some time before 17.10, but I was hoping the 17.10 rollout would banish the problem. Not so. 1:17.10.11 still gives me a 1-line terminal window.

I've just tried removing/purging/adding update-manager(-core) and all that depend on it,
then downgrading/upgrading a package to see if the terminal window's height was restored.
Nope, it's not that easy.

I'll keep hunting, but later.
>From memory, it was failing to do a sanity check on a cached window-size property found in some ~/.gconf/.../%gconf.xml, but I can't find anything likely. Could now be a different problem.

I suspect everything works fine until accidental resize below some
threshold size causes the small size to stick.  I recall thinking that a
bounds check might be backward, intending to protect against too-small,
but instead /latching/ the too-small condition.  But I don't recall if
the previous fix actually matched that hypothesis
