[Rabbit-dev] Corrupted URLs in v 4.11

[Luis Soltero]

Hi Robo,

I think it mostly happens with websites that have really long urls. 

I use www.cnn.com a lot for testing rabbit and these errors are generated very frequently using that site.  You might
try that site.  For example, i was able to generate the error just now with 3 clicks...

the web pages look ok but I think this is because there are so many urls on them that the broken ones are hard to spot. 
I did have a situation where a page did not display at all when the page url gave an exception. Refreshing the page
fixed the problem.

Another website that causes issue is hotmail.com.  If you start clicking on emails in the inbox about every 3 or 4
clicks the mesg will not display when the exception occurs. Clicking on the same mesg a second time causes it to display.  

So the error occurs frequently but is not 100% reproducible. A url that causes the error at one time will not on
subsequent execution.

here is the error generated at the www.cnn.com site.
