Public bug reported:

When I start "Hugin Calibrate Lens" from my Debian Testing Cinnamon
Start Menu, a popup labelled "calibrate_lens_gui" pops up saying "An
assertion failed!"

Hugin version: 2021.0.0+dfsg-3


ASSERT INFO:
./src/gtk/bitmap.cpp(541): assert ""width > 0 && height > 0"" failed in Create(): invalid bitmap size

Clicking "Continue" brings the same popup again. Clicking "Stop" closes
the program. So Calibrate lens is not usable.

This reminds me of an earlier bug #1909484 (2020.0.0 calibrate_lens_gui
- multiple assertions at startup) with the previous version. This one
has been fixed by the wx-widgets team (issue 18520) - they said, they
would check width/height instead bmpData. Seems, Hugin still calls
wxBitmap:Create with an invalid bitmap.
