Every time I try to download the tiles in this area, merkaartor (013.2) and 0.14pre2 close after downloading:
Downloader::go: "/api/0.6/map?bbox=11.742107,47.869553,11.778987,47.900998"

The debug-box/file shows thousands of this notEverythingDownloaded, then the software crash down:

Funny... I found out about this potential problem (recursing relations) no later than last week...

(In [16597]) FIX : Avoid infinite loop with imbricated relations (fixes #2080)
