Subject: bug#38038: 27.0.50; Emacs freezes opening tabs.
Date: Sat, 2 Nov 2019 22:41:35 +0100

Hi when using emacs in gui I can't open a new tab if I add these lines
to my config:

(set-face-attribute 'tab-bar nil
       :background "#000000" :foreground "#e5e5e5"
       :inverse-video nil)

(set-face-attribute 'tab-bar-tab nil
       :weight 'ultra-bold :underline t)

(set-face-attribute 'tab-bar-tab-inactive nil
       :background "#000000" :foreground "#ffffff"
       :weight 'normal :underline nil)

In tui there is no problem and in gdb I get this backtrace:

==================================

In gdb the bt shows:
