<p>Assuming the <code>document_close</code> assertion is coming from TreeBrowser, I notice a few places where it calls <code>document_close</code> without checking if the document is <code>NULL</code> and/or valid, especially <a href="https://github.com/geany/geany-plugins/blob/68cb7d2c0f75aef0e98b3877088473a8618c46a0/treebrowser/src/treebrowser.c#L1091">here</a> where the called function will return <code>NULL</code> if the file isn't found. This code appears to be in the path of deleting a file, though it may be entirely unrelated to the crasher.</p>
