Select Font Family Crashes
#### Summary:
I tried to do the written text in Inkscape. when I try to click to change the font (Select font family). Suddenly my Inkscape does not respond and force close.
#### Steps to reproduce:
<!-- Describe what you did (step-by-step) so we can reproduce: -->
- Have a lot of fonts installed (must be installed in per user or system-wide, can't be from dragging the fonts into those files but using Window's install option)
- open Inkscape
- Select text tool (F8)
- Write text
- Open Select Font Family (Alt + X)
#### What happened?
- Suddenly, Inkscape stops responding and crashes (see the video).

Workarounds on Linux don't work, i.e. the following do not help: disabling font samples, the 1.1-dev patch, or opening the Text and Font dialog first. Actually the 1.1-dev patch does help for the second crash (with less fonts installed).
#### What should have happened?
- Dropdown appears, no crash.
