Threema full-backup restore fails (app crash)

I am trying to restore a full backup of Threema (3.7) on Sailfish The backup includes all media and thus is 400 MB large. When I start the restore process inside Threema, the app minimizes and seemingly tries to unfold the backup in the background. But a moment later the app cover becomes transparent, so it basically crashes. When I tap the crashed cover the app restarts to the state before backup recovery. This occurs on Xperia X and on J1 the same way.

My suspects are:

  • insufficient RAM
  • aliendalvik being unable to handle multitasking features of android apps, i.e. android apps trying to minimize and run in the background.
  • some random bug

Possible solution approaches:

  • increase RAM allocation to aliendalvik (how? With no apps running I have ~2GB free RAM shown by lighthouse)
  • force app to stay in foreground (how?)

Who has experienced this or may give me an idea how to solve it?

Try to grab a log via devel-su journalctl -fal and lxc-attach -n aliendalvik /system/bin/sh and using logcat

I seem to have the same problem I'm pretty sure ram is not the issue, my backup is less than a MiB in size and it still crashes for me.

@bomo dalvik on J1 on xperia x is not lxc based and the journal does not seem to contain anything dalvik related.
