           Summary: "Battle.net Helper.exe" component of "Blizzard App"
                    crashes

Backtrace provided by the Wine error message.

Bug appears after logging into the "Blizzard App".
("Blizzard App" is currently only working in Wine-Staging - see
https://appdb.winehq.org/objectManager.php?sClass=version&iId=28855 for
details)

After logging into the "Blizzard App", suddenly a Wine error message pops up,
telling me that "Battle.net Helper.exe" has crashed. I'm attaching the
backtrace.

Nevertheless I can use the "Blizzard App" to start StarCraft 2 and it runs
well.

I guess this isn't #32342, because I got fetchmsttfonts-11.4-23.1.noarch
installed via Linux package management and I also did:
  env WINEPREFIX="${HOME}"/wines/starcraft2_x64/ winetricks_2017-12-22.sh
corefonts

OS: openSUSE 42.3 (x86_64)
