Investigation showed that when you starting to synchronize some information about collection from internet you are opening a lot of new file descriptors to the same collection.db file and finally it reaches maximum limit of number of opened files(1024 - I think it is default on all linux systems) and finally crashes with the above error.

You can use ls -l /proc/$(pgrep babe)/fd | wc -l to see number of opened descriptors of babe process once you start it
