GeDialog::GetFilename is broken in 2026.3.0 in both the C++ and Python API, returning the empty filename/string, even when a gadget holds a valid string. Plugins using dialogs which use Filename parameters are therefore currently malfunctioning when used in 2026.3.0. The issue does not exist in 2026.2.0 or earlier versions.

We will deploy the hotfix for this issue in the coming weeks.

Cheers,
Ferdinand
