"Error" dialog can appear

[Ryan J Ollos]

From time to time I see this dialog:

It seems to occur when I interact with the elements of the page before it has completely loaded. Today, I found a way to reliably reproduce the issue:

1. Go to report:1.
2. Click above the tickets column to sort in ascending or descending order.
3. When the DOM has loaded, but before the page indicates it has fully loaded, click to sort the column again.

With those steps, I can produce the error dialog about 1 out of every 3 times. It seems there are two error dialogs, because I have to click OK twice to dismiss it fully. If I disable the QuietPlugin, I never observe the Error dialog. There are no errors in the JS error console on Firefox 15.

Btw, I'm on Trac 0.12.3.

I have two other avenues to investigate:

• Whether this could be caused by the patch in #9764.
• Whether this only occurs in the presence of some other plugin's JS on the page, SectionEditPlugin, MenusPlugin, TracJsGanttPlugin or EstimationToolsPlugin.
