I've seen this on a few PCs, and there's no pattern to it, ...
Specifically, the long gap does not always follow or precede a
particular entry in the list.
These are actually two different issues. The large blank is a
very old and well-known issue.
Ah thanks; I'd been wondering about the "large blank" thing!
MVP Kelly Theriot has lots of Add/Remove Programs issues at her website.

From David Candy:
HKEY LOCAL MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Look under here in the registry; one of the icons has a negative number.
Technical details at The Old New Thing : Why does Add or Remove Programs
show a large blank space?:

From that site, it appears that positive values will bug the same way,if they don't resolve to an icon image within the file (or perhaps if
the file is not found). For example, an icon index of 15 won't work
if the file's resources only hold 6 icons.
Also from that site, the writer asks...
"Perhaps the Add or Remove Programs control panel should be more
tolerant of invalid icon registrations? Or should it stay the way it
is, adhering to the "Don't bend over backwards to fix buggy programs;
force the program authors to fix their own bugs" policy that so many
of my readers advocate? "
....to which I'd reply: Icon index is an input parameter, and all input
parameters should be sanity-checked. Exploitabiliy of icon handling
is nasty, and we've already had one such even already.
