xml parser error during upgrade to 8.04

[psl]

Binary package hint: pkgsel

Ubuntu 8.04 i386, upgrade from 7.10 to 8.04.

See attached screenshot, it shows parser error noticed during Ubuntu upgrade. It is possible that this problem is not in pkgsel package but in other package. I noticed similar errors in the past too but ever reported them...

It is possible that more packages in repository have wrong xml file. Can be run some automated test to identify them and report to be fixed?
