Hugin Calibrate Lens asserts on start

[h1repp]

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.

I can't reproduce it. Assuming this is with wxWidgets 3.2 with GTK3? And it does not happen with wxWidgets 3.1.x?
Trying to blind fix in repository.

yes, seems wxWidgets 3.2 with GTK3, See my ldd:
