From 8a25ded7585871ce579d6439baf58c5cd0f6812b Mon Sep 17 00:00:00 2001 From: Christoph Wurst Date: Thu, 8 Oct 2020 19:52:29 +0200 Subject: [PATCH] Fix undefined index and consequential damages in versions code If the user has no space and there are no versions, there won't be an `all` index in the versions entry. Hence this triggers a warning and becomes `null`, afterwards `count`, `foreach` and friends will happily throw even more warnings and errors because they don't want to play with `null`. Thus adding a fallback to an empty array.
