[Verse-dev] Yet Another Bug in Verse

[Jiří Hnídek]

Hi,
I have temporary solved my problem described here with sending new
vertexes with some not used ids, but I really think, that verse server
should be master of ids. I will try to write about it more soon. I will
look at your patch tomorrow, because I have to go home now.

Have a fun in Boston!
