+Subject: [PATCH] Fix session restore
+
+Since https://commits.kde.org/kxmlgui/8c9fb02a1d37672b26a03a9dd9e8675743deb269
+KXmlGui only triggers a session restore for a window when the
+session config contains a "NumberOfWindows" key with a value >= 1.
+This commit adds such a key to the Dolphin session config, which
+fixes the Dolphin main window restore for KXmlGui versions
+containing that commit.
+
+BUG: 502770
+
+
+(cherry picked from commit c0bf226aa1cc02c9bffff1ec05e07a255d8d2f6e)
