What is the iPhone Firmware package supposed to do?

I had it installed (no idea why) and it began to cause my keyboard to fail.
If you have an application open (say like Notepad) and held down on the screen it would start inputting random characters (including behaving as if you scrolled up and down) very fast.

I essentially made cut and paste impossible, since you couldn't hold down long enough to start selecting text.

Removing the application (and it's two dependencies) then rebooting fixed the problem.

More troubleshooting and it was Libxml2 and SQLite 3.x libraries.

Cydia had a second round of updates for these day before yesterday and that version seems to work now.

Starting to think it is random.

I just removed libxml2, SQLite3, and iPhone Firmware today and it didn't clear the problem.

I ended up removing vnc, mobilesubstrate and several other things today to clear the problem.

I even rebooted after removing all that.

Is no one else having this quirky problem?
