checker. Systems where Suomi-malaga 1.10 is installed seem to be affected by 
this. Likely older versions have similar issues that just have not been 

If you are distributing libvoikko + Suomi-malaga 1.10 and use the grammar

following trivial patch:


I will try to come up with a proper fix and then release libvoikko 3.3.2 with 
it. Unfortunately the real fix may not be safe and simple and thus this 
workaround might be better for most of you.
