Catastrophic failure in KSudoku

[Ian Wadham]

It appears that KSudoku is failing catastrophically. Only the most vanilla puzzle types can be selected
(i.e.  Classic Sudoku nxn and Roxdoku nxnxn). All others fail to create their data-structures from XML
files and so fail to generate a puzzle and display it (e.g. XSudoku, Killer Sudoku, Aztec, Samurai
and many more).

For more details, please see https://bugs.kde.org/show_bug.cgi?id=405422, especially comment #3.

This was reported by Duncan, who builds KF5 and apps from live-git and has just noticed the problem
appearing in the last week or two --- more recently than any changes in the KSudoku source.

Please can someone who has access to builds and executables of the latest development (HEAD)
KSudoku code check if they can reproduce this error? You just need to run KSudoku, select Aztec
puzzle-type (for example) and click on “Generate A Puzzle”.

Thanks in advance,
Ian Wadham.
