I've figured out why this error did not happen to me at my home PC. I'm
using desktop-save-mode, and at work it loaded some buffer that enables
yasnippet support, thus immediately producing error. At home I mostly work
with text files, that I don't enable snippets, so error got unnoticed.

I've set `debug-on-error' to t, and here's the trace:
