winheight cannot be smaller than winminheight

Nice plugin!

I have these settings in my .vimrc courtesy of Gary Bernhardt's Destroy All Software screencast series.

set winwidth=84
" We have to have a winheight bigger than we want to set winminheight. But if
" we set winheight to be huge before winminheight, the winminheight set will
" fail.
set winheight=5
set winminheight=5
set winheight=999

When I go to load up a saved session I receive the following error:

I'm not sure what is setting winheight=1, but that isn't in my .vimrc. Is that something this plugin is setting? It doesn't seem like it matters much, the sessions load fine, but it's obviously an eye sore / slow to have it error out each time I load up a saved session.

Thanks for taking a look!

Reproduce the error with the reported .vimrc settings and a saved session, then inspect how obsession writes and loads session files. Confirm which setting produces winheight=1 and verify that loading the session no longer reports the error while preserving the expected window settings.
