Open font list causes crash (fc-list finds 4662)

Steps to reproduce:

  • Install a lot of fonts. I had a couple miscellaneous fonts, the Noto fonts, and the ofl folder of the Google free fonts. fc-list | wc -l reports 4662
  • Open Inkscape (text and font dialog should be closed at startup. If not, close and restart)
  • Switch to text tool
  • Open the font list

What happened?

Crash

(org.inkscape.Inkscape:30637): Gdk-ERROR **: 16:43:36.248: The program 'org.inkscape.Inkscape' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 4566 error_code 11 request_code 12 (core protocol) minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)

@CRogers experienced a similar issue (well, same issue, different crash message, (Details: serial 22539 error_code 11 request_code 130 (MIT-SHM) minor_code 5), only 2863 fonts listed). see https://chat.inkscape.org/channel/team_devel?msg=dr2fiuHXfkQCkXfAB

Others were not able to replicate.
Including me (https://chat.inkscape.org/channel/team_devel?msg=YAsS2tuLYh57sm8ot), however I had screen tearing, and the following error message:

(inkscape:17930): Gdk-WARNING **: 10:45:05.095: Native Windows wider or taller than 32767 pixels are not supported

vlcsnap-screentearing

I can no longer replicate the screen tearing.

Workaround

Open the Text and Font Dialog first, or just

Have less fonts (4653 doesn't crash on my system)
