Indeed, I can reproduce the problem with the log file you provided.  It
works for me because I use file_line_error_style = t in
/etc/texmf/web2c/texmf.cnf.  But that it works in that case is also a
coincidence: not my test.tex is on top of the stack as would be correct
but test.aux happens to be there which is good enough.

And you are right that the problem is in

  Package hyperref Message: Driver (autodetected): hpdftex.

where the closing paren removes the top of the TeX-error-file stack
where it shouldn't.

This minimal patch makes it work again for me in "normal" and
file_line_error mode.

I just ignore closers that are followed by a colon and I also handle
each closer separately.  Not sure why the ")*" was there before, but the
result was that if multiple files where closed, only one was removed
from the stack.  Of course, that's better than having the correct file
already popped off the stack, but still it may report the error in the
wrong file.
