Pad stuck on Loading status after paste some text

I have suffered several times this annoying behaviour. From time to time, I cut and paste some text (even inside the pad itself) and the pad goes empty and shows Loading message forever.

Uncaught Error: mismatch error setting raw text in setDocAText

Taking a look into older issues I found #885 and #769. This should be addressed, but seems like it is happening again. At least on my deployment.

node version: v0.10.29 npm version: 1.4.21 etherpad-lite version: 1.6.0

My guess is that the paste itself caused the error, so existing pads will keep being stuck at “Loading”.

Looking at the list of plugins, the only one that looked suspicious of causing this issue was ep_linebreak. If you have some time, could you install this plugin on your new Etherpad instance and try to copy/paste some lines with manual line-breaks to see if you can reproduce the error?

Thanks, @pabelenda !

Finally I decided to remove ep_linebreak on the production environment and, since then, no issues were reported.

Anyway, on the testing environment, with ep_linebreak installed, I am not able to reproduce the thing.

At this point I think we can close this issue. Many thanks for the help 😃
