<p>I don't really know anything about GtkTreeView stuff, but maybe one of the calls to <a href="https://github.com/geany/geany-plugins/blob/68cb7d2c0f75aef0e98b3877088473a8618c46a0/treebrowser/src/treebrowser.c#L780"><code>treebrowser_tree_store_iter_clear_nodes()</code></a> is passing an invalid iterator and/or one with no parent?</p>
<p>If anyone can <a href="https://www.geany.org/Support/Bugs" rel="nofollow">provide a backtrace</a> with debugging symbols for Geany/TreeBrowser installed, it might be easier to track down.</p>
