I imagine

sudo aptitude reinstall texlive texlive-base texlive-base-bin
texlive-base-bin-doc texlive-common texlive-doc-base
texlive-extra-utils texlive-fonts-recommended
texlive-fonts-recommended-doc texlive-generic-extra
texlive-generic-recommended texlive-humanities texlive-humanities-doc
texlive-latex-base texlive-latex-base-doc texlive-latex-extra
texlive-latex-extra-doc texlive-latex-recommended
texlive-latex-recommended-doc texlive-math-extra texlive-pictures
texlive-pictures-doc texlive-pstricks texlive-pstricks-doc

would give dpkg a good workout without risking damage to any vital
part of the system.

Also since others mention that fsync may be related, I wonder: does
this problem seem to be ext3 or ext4 specific?
