Not sure what is going on (and not sure how to reproduce this), however:

From your log, you got the problem when you pressed BackSpace key.
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.
