#54 Nearly infinite loop in KTable.updateScrollbarVisibility

[Cédric]

One of our KTable makes the GUI freeze for about one minute when the table input changes.

It seems this bug occurs when the content of a text cell is very long, lets say more than 1000 characters.

Here is an extract of the attached stack trace:
