Hi there.

I run into the same problems, when running the PCMAIL mail reader.
Saveconf.el had saved some buffers, but on new startup the respective
packages are not loaded. So various variables and/or functions are void
for that buffer. I made the following changes to saveconf.el, which
basically modify the regexps for saving the windows and buffers.
