[Debian-med-packaging] Bug#927387: invesalius: crashes after splash screen

[David Paul]

Package: invesalius
Version: 3.1.99992-2
Severity: grave

Dear Maintainer,

When attempting to run InVesalius for the first time, I am presented
with the first-run language selector followed by the splash screen,
but no window ever appears and the invesalius3 process remains active
until manually terminated. Subsequent run attempts differ only in that
the language selector is not presented and the invesalius3 process
terminates on its own.

The following is the console output:
```
$ invesalius3 -d
