Hi,

@JKB could you check if commit b167c41d1b works for you?

I have a similar issue when I open the footprint browser from within the symbol editor and git bisect came up with commit 7e2e39ce304.

The current master shows a dialog with a warning (I do not remember the message) before opening the browser (it does not crash).

I was about to write a bug report but I think it might be the same issue.
