--- Comment #2 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming.

The crash is within CEF3 renderer processes, 'libcef.dll'

https://code.google.com/p/chromiumembedded/wiki/GeneralUsage

--- quote ---
CEF3 runs using multiple processes. The main process which handles window
creation, painting and network access is called the “browser” process. This is
generally the same process as the host application and the majority of the
application logic will run in the browser process. Blink rendering and
JavaScript execution occur in a separate “render” process.

Dumping the version info from 'libcef.dll' with 'resourcehacker' yields:

Fortunately it seems they use an unmodified CEF3 build 3.2062.1838 after
comparing the provided downloads and the API hash which helped me a bit during
debugging and to nail it further down.

It seems the problem stems from font subsystem being not happy about the
returned font facenames requested.
Not a surprise - similar situation as with Webkit based apps.

'winetricks -q corefonts' (or Arial font alone) prevents the crash.

Also Patrick's patch https://bugs.winehq.org/attachment.cgi?id=50082 from
https://bugs.winehq.org/show_bug.cgi?id=32342#c19 helps here.

Resolving as dupe.
