--- Comment #10 from noabody at yahoo.com ---
Problem is in:
$HOME/.wine/drive_c/Program Files (x86)/KeePass Password Safe
2/KeePassLibC64.dll

Rename file to:
$HOME/.wine/drive_c/Program Files (x86)/KeePass Password Safe
2/KeePassLibC64.bak

And keepass2 starts normally.  Any version of keepass downloaded from official
channels has a very different layout than if built locally, whether via mono or
vs2017.  Official builds look like this:

KeePass.chm
KeePass.exe
KeePass.exe.config
KeePassLibC32.dll
KeePassLibC64.dll
KeePass.XmlSerializers.dll
License.txt
ShInstUtil.exe

Personal builds look like this:

KeePass.exe
KeePassLib.dll
KeePassLib.xml

Pretty big difference.  Not real sure why that is but all of the personal build
I did looked like they were "AnyCPU" or combined architecture, which might just
default to non-64bit.  Presumably KeePassLibC64.dll wants to use enhanced CPU
instructions, wine bycrypt advertises their availability, gnutls provided the
capability, and the CPU cannot process.

I like to think of the K10 cpu instruction set deficiency as:

Keepass wants it (one of the following SIMD/SSSE3/AES-NI/AVX/SSE4.1)
Wine says it has it
gnutls provides it
cpu fails to process it
