Package: libsqlcipher0
Version: 3.2.0-2
Severity: important

Dear Hans-Christoph,

This could be severity grave, but as I did not verify whether other
applications using libsqlcipher0 crash, I am setting it to important for

Sometime ago qTox started crashing after entering profile password on my 
Debian setup. This may have been shortly before Christmas and may relate
to your change in 3.2.0-2.

I reported this first with upstream:

segmentation fault on startup #4054

And after several attempts with compiling qTox myself and trying to compile
sqlcipher library myself (which failed on my system for 3.4.0), I found that
downgrading libsqlcipher0 to

fixes the issue for me.

So it appears to me that this is a distribution side issue which may be
related to the transition to openssl 1.1.

Steps to reproduce

1) rm -r ~/.config/tox (make backup first!)
2) start qtox
3) Create new profile, I used user "test" with password "12"

You do not need to compile qTox yourself, but can install packages as
described in:

The bug happens with qtox package, with qtox-alpha package and with self
compiled qtox from git 6b51381980e4d742efff0905a697040efbcce049

For now I will pin the libsqlcipher0 package to the older version.

Here is one of the backtraces from qTox copied from my upstream bug report:
