Exporting opening lines from menu item Export fails and logs bug in bug.log.

[kes]

Ubuntu 24.04.3 LTS Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux Lucas Chess R 2.20c version R 2.20c

In opening lines, trying to export all lines to pgn (using menu at top, "Export") -- it doesn't matter whether there is just one line, or there are multiple lines, the same IndexError occurs in bug.log (below).

There is an easy workaround: exporting by right clicking on a line and selecting export in pgn format as mainline does export all the lines, and with the selected line as the main line as expected.
