I usually update my roundcube mail instance every day to the latest revision in SVN. I updated like normal this morning to revision 2301 and I was unable to read any email using roundcube. After clicking on a message I got the "Loading..." message at the top and roundcube just timed out after a while on every message. After reverting back to revision 2298 I was able to read email again like normal. I was not sure where to report this so I thought I should post here. If there are any more details you need please let me know.
Thanks!
