Mixer app startup is slow.

Sorry for the late reply.
>Could you please tell us, approximately, how much time it takes for the slidebar to appear ?
When I tried Guppy 7.0.2 it does not show up for the time I wait.
In the case of Guppy 7.0.1, it may take 17 seconds or soon.

There is no opportunity to pug an Bluetooth USB dongle.

@minori:

This message is scary:

A needed file is missing, letting us think of a rootfs corruption or a build/install issue.

@minori: Did you read my questions ?

@Sebastien Douheret
Sorry, I uploaded journalctl log now.

Could you please tell us, approximately, how much time it takes for the slidebar to appear ?

Also, (if not already done) would you have the opportunity to pug an bluetooth USB dongle on the board, and tell us if that makes a difference ?

Meanwhile, we will try to reproduce it.
