[Bug 1765686] Re: gnome-shell crashed with SIGSEGV in g_str_hash() from g_hash_table_lookup_node()

[Daniel van Vugt]

"Incomplete" makes sense to me because it appears the problem stopped
happening after 3.28, and not at all in 3.30. We will need more time to
verify that's really true:

and if so then this is "Fix Released" already.

  It seems to be reproduceable, if I load a wider filearea with
  different filesystems (ntfs and ext4)
