[Pkg-matrix-maintainers] Bug#901858: nheko segfault on login

[Red Omen]

Package: nheko
Version: 0.4.2-1
Severity: normal

Dear Maintainer,
When connecting to matrix.org nheko segfaults immediately after clicking login.
Removing ~/.cache/nheko and ~/.config/nheko allows me to re-enter my info but
it still segfaults on login.

Here is a backtrace from gdb:
