Screenshot for kwrite showing wrong rendering

Description of problem:

Conjunct "യ്യ" and "വ്വ" when used after chillu conjuncts, it gets combined
with the chillu resulting in wrong rendering. ie,
Conjunct യ്യ = യ + ് + യ [ 0D2F + 0D4D + 0D2F ] and
Conjunct വ്വ = വ  + ് + വ [ 0D35 + 0D4D + 0D35 ]

Also,
When any consonant is combined with 0D2F or 0D35 using 0D4D, gives the
following result (Here, consonant ക [0D15] is used) :
ക  +  ്  +  യ  =  ക്യ  [ 0D15  + 0D4D  + 0D2F ]
ക  +  ്  +  വ   =  ക്വ  [ 0D15  + 0D4D  + 0D35 ]

Thus, when conjunct യ്യ or വ്വ is used after any chillu conjuncts, say ന്‍, the
first 0D2F/0D35 is getting combined with ന്‍ and giving out wrong results.

Version-Release number of selected component (if applicable):
qt-4.5.3-9.fc12
kdebase-4.3.3-3.fc12

How reproducible:
Always 

Steps to Reproduce:
(i) For Conjunct "യ്യ"
1. Open kwrite
2. Type 0D28, 0D4D, 200D, 0D2F, 0D4D, 0D2F

(ii) For Conjunct "വ്വ"
1. Open kwrite
2. Type 0D28, 0D4D, 200D, 0D35, 0D4D, 0D35

Observe the wrong rendering for above combination.

Actual results:
When conjunct "യ്യ" and  "വ്വ" is used after chillu, they get combined with the
chillu and is thus wrong rendering. Attached screenshot with kwrite showing
this wrong rendering.

Expected results:
When conjunct "യ്യ" and  "വ്വ" is used after chillu, they must not get combined
with the chillu. Attached screenshot with gedit showing correct rendering.

Additional info:
5 Chillu conjuncts are:
ന്‍  =  ന +  ്  + ZWJ  [ 0D28 + 0D4D + 200D ]
ര്‍  =  ര +  ്  + ZWJ  [ 0D30 + 0D4D + 200D ]
ണ്‍  = ണ +  ്  + ZWJ  [ 0D23 + 0D4D + 200D ]
ള്‍  = ള +  ്  + ZWJ  [ 0D33 + 0D4D + 200D ]
ല്‍  =  ല +  ്  + ZWJ  [ 0D32 + 0D4D + 200D ]
