I fixed in Geany in this commit: https://github.com/geany/geany/commit/8f489fc9fbab8a8c197f40536fac8ebd74c430eb So if you pull from Geany's repo and rebuild, even before applying the patch, the toolbar problem should be fixed, but probably best to apply the same changes as in that commit the plugin as well.
