Speak fails on launch without net connection

[cjb]

According to this OLPC bug, Speak is crashing on launch with no net connection:

​http://dev.laptop.org/ticket/9945

It seems obvious to me that Speak should never depend on a net connection. What's going on?

Speak was switched to services(​http://wiki.sugarlabs.org/go/Activity_Team/Services) to install missed gst-espeak plugin which is missed on XO.

This issue with disabled connection after downloading but before first launch was predicted but can be fixed only from shell side(see offline mode in ​http://wiki.sugarlabs.org/go/Features/Zero_Install_integration). I guess in most cases it should work as is(since user downloaded activity from ASLO), other cases(like deploying previously downloaded from ASLO activities) could be treaded in separate way e.g. ASLO or something which deploy "offline" ASLO activities can automatically bundle all 0install dependencies.

It already could be done somehow on ASLO, since we have user's arch from useragent string and language from ASLO's language selector and I'm working on it. In the rest cases like complicated deps that require not only arch to resolve the full deps tree or in cases when users already have activity dependencies ​http://wiki.sugarlabs.org/go/Features/Zero_Install_integration could pass "online" mode flag in Browse's useragent string

hmm.. it will break mirroring workflow since downloaded .xo could be different for the same activity. I guess better tweak Browse to split .xo downloading to two phases - binary less .xo and 0install deps.

I'm going to implement such fix for 0.82+ Browses.

I've reverted CB-9 and Speak-12 to previous versions and closing this ticket since the whole Sugar Services will be accessible from development environment(somehow).
