Server metadata contains non-string types

[kinow]

Hi,

Debugging a simple example, I noticed some of the values in the metadata were not strings. There was at least one dictionary, which would explain #7 (I was having the same issue).

I tried to find a place to create a test, but couldn't decide if it was necessary, nor where to create one if so. Let me know if it needs a test (some pointers on where/how to create it would be welcomel; I'm not very experienced in Julia.)

Thanks! Bruno
