Do you need to close any dialogs that appear, in order to trigger this? (In my linux debug build, I get a few modal "this search engine isn't supported by nightly and can't be installed" popups, and a file-picker dialog asking me to open a file.)

Also, how long did you need to wait before the assertion-failures in your attached log?

Don't remember, sorry.

> I get a few modal "this search engine isn't supported"

There's a workaround for that in bug 839736 comment 1.

> Also, how long did you need to wait

An hour or so, iirc.
