<p dir="auto">If there is a mistake in code of an observer the tracback is similar to this:</p>
<pre><code class="language-console">Observer '&lt;__main__.SimpleGroupWindow object at 0x11c8b5590&gt;' with '_currentGlyphChanged' failed: 'NoneType' object is not callable
</code></pre>
<p dir="auto">If the code is more than a few lines, it's very hard to find out where the problem originates without knowing the line. Is it possible to add the line number and more info to the Traceback?</p>
<p dir="auto">Thanks</p>
