Even though Gerd also speaks German, I think its better to continue in English. I am quite sure that this is the same bug then. Your map does not crash because it find another POI first. I also sometimes have two POI for the same thing - one for finding it via a category POI search, the other for the symbol in the map. I do wonder if you have two POI the order in the style matters? If you change the order they are created - does it crash?
Could it be that only 0x1234 POI are affected, but the newer 0x12345 types not? As soon as it finds 0x12345 it does not crash?
Lets take Verbier Village - it is not a ciy POI
I use: highway=bus_stop | amenity=bus_stop | highway=busstop | amenity=busstop | railway=bus_stop {set name='bus_stop ${name}' | 'bus_stop' } [0x2f17 resolution 24]
for that one.

I have the rule:
0x1c01 resolution 24 continue]
[0x11607 resolution 20-21 continue]
[0x1151f resolution 22-22 continue
[0x1151f resolution 23-24]]
However the first one in my map obviously is 0x1c01 - an old type.
The other ones are a bit bad examples I noticed - because there exists several entries in osm data that could be found with identical name. However I have found no actual city only poi where it crashes - Saas Fee also has other POI named the same. So maybe they cause a crash.
