The real reason, as it turned out, was not a code completion request.
I typed the following lines in the editor in a class file:

#1   List list = null;
...
#10  Collection c = (Collection) ...error occurred here!...
#11  list = new ArrayList();

Error occurred while typing the cast at line #10.
It prevented me from typing the complete right hand expression.
I had to remove the (Collection) cast, and insert it after completing the right
hand expression.
Line #11 had already been typed previously!
The error won't occur if I comment or delete line #11.

The error dialog keeps on spawning everytime I recreate the same situation.
