Subject: Fix assertion when canceling file dialog
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=1cbcb303536800d889a45e8b1f286594987a6686;p=features.git

Fix assertion when canceling file dialog

Without this patch, when a file has to be loaded (for example,
after "Document->Settings->Local Class" or "Insert->Graphics")
and the file dialog is canceled, both Qt5 and Qt6 assert:
ASSERT failure in QList::at: "index out of range"
