Kai,
From what you are describing gnus-agent-fetch-selected-article updates
the internals correctly.  The problem has to be in its call to
gnus-summary-update-article-line.  I've already found, and I thought,
fixed a problem in this call.  There must be something else going
wrong.  Can you step through it to see what is happening?  What
happened before was that g-s-u-a-l jumped to, and updated, the wrong
line in the summary.
