Bug summary

During a recent GitHub Actions workflow for unrelated pull request #29721, the following error appeared:

E           gi._error.GError: gi-invoke-error-quark: Could not locate g_option_error_quark: dlopen(libglib-2.0.0.dylib, 0x0009): tried: 'libglib-2.0.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibglib-2.0.0.dylib' (no such file), '/usr/lib/libglib-2.0.0.dylib' (no such file, not in dyld cache), 'libglib-2.0.0.dylib' (no such file) (1)

Code for reproduction

This occurred for Python3.12 and Python3.13 on MacOS 14:

• https://github.com/matplotlib/matplotlib/actions/runs/13788406404/job/38561789129
• https://github.com/matplotlib/matplotlib/actions/runs/13788406404/job/38561789705

Actual outcome

See the error in the main description and linked build logs.

Expected outcome

The tests should pass as expected (the error appears to be a transient failure to locate/load a dynamic library file).
