Building latest releases and errors

I am learning about how Online works internally and and the same time 
trying to build a Fedora package for it.

My first try building and running it in my Linux user session gave no 
problems, See https://twitter.com/robmv/status/769739549589241857 . For 
it I used collabora related tags and needed to use LibreOffice 5.2 
instead of Fedora provided 5.1 because a new export of LOKit that is not 
in 5.1 (It would be nice to list that requirement).

As this is for a Fedora package it is common to work on the cutting edge 
so I switched to 1.9.2 but this time my test build gave a non fatal 
JavaScript error, the JSON protocol documentation for lokitversion 
message says that there is data but the server was sending only 
"lokitversion". I did a hack just to skip that error on ClientSession.cpp

> // Send LOKit version information
> std::string lokVersionStr =
>     "{ \"ProductName\":  \"XXX\", \"ProductVersion\":     \"" + version +
>     "\", \"ProductExtension\": \"xxx\", \"BuildId\": \"" + hash + "\" }";
> sendTextFrame("lokitversion " + lokVersionStr);

But hacking this fix doesn't solve fatal errors loading a file using 
--o:storage.filesystem[@allow]=true

Are tagged releases like 1.9.2 stable enough? Same problems with master 
(That return that the version is 1.9.0, older than the tag 1.9.2). What 
tag/branch is recommended?

Thanks in advance
