When I generate a tree, I get some strange empty nodes (more details here).

Any suggestions why this might be the case?

The relevant part of the template looks like this (but in another language):

!style="vertical-align:top; text-align:right"| Parents:
|{{#if: {{{parent1|}}} | {{#genealogy:parent | {{{parent1}}} }} }}<!--
-->{{#if: {{{parent2|}}} | <br />{{#genealogy:parent | {{{parent2}}} }} }}<!--
-->{{#if: {{{parent3|}}} | <br />{{#genealogy:parent | {{{parent3}}} }} }}

In fact it seems that the problem is non-Latin alphabet. If all the names are in Cyrillic, some weird loops are created. More details here.
