[Evolution] Very Annoying Behaviour of Keyboard Input

[Martin Bitter <martin bitter t-online de>]

Hello!

I'm using Evolution  3.2.3 with Kubuntu/Ubuntu 12.04.4 LTS precise
pangolin on a i686 athlon machine with the KDE plasma desktop.

Short time after installation EVO shows _sometimes_ (any few weeks by
daily use) this behaviour:

Keyboard input in fields (like subject, addresses and so on) isn't
recognized. Clicking is well recognized. The only solution is to restart
EVO.

That was some month before.

But now it has become the most usual behaviour i.e. the period for
'sometimes' has shortened. It happens now multiple times a day and makes
Evolution nearly unusable.

Any suggestions?

Regards Martin
