This may be a flaky that you can't do anything about, but I thought I
should report it anyway....
On Friday, I upgraded to tetex-dvips-1.0.7-25 from the previous Rawhide
version. After the upgrade, "rpm --verify tetex-dvips" reported that the
MD5 checksum on /usr/share/texmf/fonts/vf/ptex/a2mor2-min10.vf was
incorrect. When I ran "rpm -U --force tetex-dvips-1.0.7-25.i386.rpm" to
reinstall it, the problem went away.
Haven't reproduced this yet.
Still can't reproduce it. Please reopen if you find it happening again.
