Hi,
I have submitted a patch for review:
https://gerrit.libreoffice.org/3095
To pull it, you can do:
git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/95/3095/1
fdo#62094 - fix infinite loop in radio button group iteration.
Simplify the code too - we copy the vector anyway, so reversing it
should be cheap.
