I'm not familiar with Ibuffer; perhaps someone else can help here. The error
message is telling you that `c' is not a function.
If someone else doesn't have a suggestion, try: (1) loading the source files
(e.g. ibuf-ext.el), not the byte-compiled files (e.g. ibuf-ext.elc), and then
(2) `M-x debug-on-entry RET ibuffer-switch-to-saved-filters'. Then step through
the debugger using `d' and `c', to see where the problem is.
