[Ardour-Dev] ardour3 segfault due to gtk.rc

[Robin Gareus]

Hi,

ardour3 rev9563 segfaults on startup (before showing any windows) with
both ./ardev and ./ardbg.

Before I start digging (libgtk version, trying to install it instead of
running from source-folder, reading ardour3_ui_dark.rc)

Is anyone else seeing this issue? Any hints?

The last version I've tested and can confirm to be working is rev 8980.
