Description of problem: I guess I was trying to change input method by ctrl-space and so on. Not sure how to reproduce this in detail.

The candidate list is cleared when press Esc and Ctrl+comma and etc. I tried some tests but I could not reproduce your problem. Since you give the table->candidates->len is 0, I can avoid the problem but it would be great if you could find the reproducing steps to fix the root cause.
