Notes

Upstream stable is 3.59.2. This may already be fixed there.

Start by reproducing the crash in Evolution by opening a mail preview and clicking the media permissions menu, then check whether it still occurs in the reported upstream 3.59.2 version. Use the g_str_hash backtrace as the initial investigation point; done means the media permission action no longer causes a segmentation fault or the package is confirmed to contain the upstream fix.
