Bote fails to start at first run after update

[user]

After the update to 0.9.21, i2p-bote did not start.
Looking into the logs I see:

Trying to start it manually, gives the following error in the web console:
java.lang.IllegalArgumentException?: Bad temp directory: /tmp/i2p-daemon/i2p-cFkskYum.tmp/jetty-work-i2pbote776606184

I had that error before and then it was fixed by a router restart.
I don't remember well, but maybe last time I had it, it was also right after router update
Since this is the second time it occurrs it might be a bug with i2p and not just my computer being in the mood for getting on my nerves.

I ran -22-rc before and it started fine.

Also this time, a simple router restart fixed it.

May be apparmor related. (My rules may need some relaxing)

But I have selected no, as reply to the AppArmor? question in dpkg-reconfigure i2p…
