I am using dovecot (see dovecot -n output below) with metadata plugin in my own plugin. I want to insert and delete some large metadata (>4KiB). It seems, that the delete in a second call of my plugin smashes the file dovecot.dict in users dir:

That's an error in dict-file.c, file_dict_refresh():

while ((key = i_stream_read_next_line(input)) != NULL && (value = i_stream_read_next_line(input)) != NULL) {

If reading the value requires reading from the stream (because the value doesn't fit into the input buffer), the key is overwritten. The attached patch duplicates the key before reading the value.
