White page (no HTML) when trying to edit a question

Question

I think I've found a possible bug on AskUbuntu. Earlier, I was trying to edit this question.

Here is a screenshot of it:

As you can see, the webpage looks fine and normal. But when I click on the edit link to edit it, I immediately get the message: "There is a pending suggested edit in the queue. Try again in a few minutes."

All it would be also fine and normal, but...

...the above mentioned message shows up on a completely blank page. No HTML, no website. I had to hit the back button in the browser in order to get back to "reality".

I'm a bit puzzled. I don't even know what to ask. I guess that there is a slight technical problem with AskUbuntu website and I feel the need to report it. This problem may occur to other users too.

Answer 1

This problem is a very rare case, which probably won't be addressed anytime soon as it would probably prove to be complicated.
Normally, when you open a post that still has a pending suggested edit, the edit/improve this question button is completely removed.

Although, instead of having a fix for this issue, a feature request to show a more "beautiful" layout for errors may prove to be more friendly. As these errors seem to have this blank page as the current default layout.
Another similar example: Bug in the audit system?

Basically what happened in your case is the following:

• You and someone else opened the Question's page
• Both of you saw an issue with the post, so you wanted to improve it by editing it.
• That other person was slightly faster and had already submitted a pending edit suggestion.
• While you still have that page opened, and you still haven't refreshed, you clicked on the edit link.
• Since the Stack Exchange engine does not allow more than one suggested edit at the same time, you got the following error:

  There is a pending suggested edit in the queue. Try again in a few minutes.
