Segfault when creating a new solid color

[mxa]

This happens on Shotcut-20.04.12 and the Shotcut-200614.glibc2.14-x86_64.AppImage, tested on Linux Kubuntu 20.04.
When adding a new solid color Shotcut ends with a segfault.

I reproduced this only when using JACK and the exact steps shown. There are a few different ways to avoid it as workaround:

• use Open Other from the main toolbar
• do not use JACK
• do not first open an existing project
• use Properties to change an existing color instead of Open Other

Thanks @ddennedy for resolving this so quickly, I really enjoy working with shotcut!
