I think this problem would occur with Ubuntu as well so I hope ths isn't
OT (being a Kubuntu question).
I recently re-installed Kubuntu 7.10 (gutsy gibbon) after running 7.04
very happily. The reason I re-installed and didn't just upgrade is
because I started using the 64bit program as I now have an AMD 64 athlon
based computer. I have two problems (meanwhile :-) ) that I can't solve.

1. When adding a program OR downloading upgrades I get the following
message (during the installation process).
"There was a problem commiting changes. Possibly there was a problem
downloading some packages or the commit would break packages."
The programs or upgrades APPEAR to work after this message but I have no
idea how to prevent this message or what it means.

2. The other problem occurs as far as I can see ONLY in my e-mail. I use
(and have always used) Thunderbird. When receiving hyperlinks in an
email correspondence I cannot click on the hyperlink and go to the site
mentioned. Nothing happens when clicking on the hyperlink. The browser
(Firefox in my case) doesn't open or react to the hyperlink click. To
make the hyperlink work I have to manually open Firefox and then copy
and paste the hyperlink. When clicking on hyperlinks within the browser
they do open the clicked site. This problem (as I said) only occurs from
within my e-mail although I must admit I didn't create a hyperliunk in
OOo and try it.
As I am now at work that experiment will have to wait until I get home.
Hope somebody can help with these two problems.
