the apl model with empty checkpoint condition that crashes amarok

amarok allows me to generate an incomplete model of APL using an
incomplete "checkpoint" constraint.

to reproduce start with for example this APL model :
pascal@minipc:~$ cat Musique/classiques3.xml
<?xml version="1.0" encoding="UTF-8"?>
<playlistgenerator>
<generatorpreset title="classiques3">
<constrainttree>
<group matchtype="all">
<constraint field="genre" comparison="3" invert="false" type="TagMatch" value="Classical" strictness="0.1"/>
</group>
</constrainttree>
</generatorpreset>
</playlistgenerator>

then just
add a "checkpoint" constraint to the constrainttree (see screenshot)
but do not select anything as checkpoint parameters,
just adjust strictness of checkpoint to exact
click OK

the new model is saved

when editing this model you see the 2 constraints are there as in the
screenshot but when exporting this model to a file the "checkpoint"
constraint is absent !

now try to execute this model ==> amarok crashes

running in debug mode gives this upon executing this incomplete model :

pascal@minipc:~$ amarok: [APG::ConstraintSolver] New ConstraintSolver with serial number 967666005
amarok: [APG::ConstraintNode] new constraint node at 0x31de3f90 with parent at 0x2f6023f0
amarok: [APG::ConstraintSolver] Domain has 4376 tracks
amarok: [APG::ConstraintSolver] Running ConstraintSolver 967666005
amarok: Fatal IO error: client killed
Unable to start Dr. Konqi
Not forwarding the crash to Apport.

Reproducible with 2.9.82. Let's see if I'll come up with a fix sometime
