Shows uncutted subject with was-speration

Version:           4.7 (using KDE 4.7.0) 
OS:                MS Windows

When subject is changed correctly with a was-separation, KNode doesn't cut the was-section in round clamps in the follow-up

Example:
subject "This is a new test (was: the old test)"

Correct would be now the follow-up-subject:
"This is a new test"

But KNode shows the uncutted version:
"This is a new test (was: the old test)"

Reproducible: Always

Steps to Reproduce:
Generate a follow-up to a posting with separating the old subject with "was: " in clambs.
Then do a new follow-up at that last Fup, the subject will not be cutted in the right way.

Actual Results:  
Knode doesn't cut the subject-text in clambs.

Expected Results:  
It schould cut the subject at the first clamb.
