The start center lists recently opened files (some of which may no longer exist at that location any more). Starting in LO 24.2, if I try to open one of these non-existent files, my Ubuntu/gtk3 machine duplicates the error dialog. Both dialogs display the same message "~/Downloads/filename.docx does not exist." The dialog also duplicates with SAL_USE_VCLPLUGIN=gen instdir/program/soffice. This started with LO 24.2 commit 86c682273d907c77404637c89e584047de1c1099 Author: Mike Kaganski on Sun Nov 26 20:18:34 2023 +0300 tdf#96401: allow to detect a broken ZIP package [Note: earlier in 24.2 there was no error message at all, due to Noel's commit e3c961e6a3917d95534652e0f982918cc1079015 which was soon reverted.]

The start center specifically is irrelevant. The same is seen for file - recent documents (or even file - open - if the pre-selected file is then removed).
