Doesn't (setq debug-on-error t) give you a backtrace of the
'split-window' error?

Note that 'list-timers' usually pops up the *Disabled Command* buffer


You have invoked the disabled command list-timers.
Beware: manually canceling timers can ruin your Emacs session.

Do you want to use this command anyway?

You can now type
y   to try it and enable it (no questions if you use it again).
n   to cancel--don’t try the command, and it remains disabled.
SPC to try the command just this once, but leave it disabled.
!   to try it, and enable all disabled commands for this session only.


dialog which might be creating the problem you see.
