Please, add sample mail as attachment to the ticket. What means it hangs? Javascript error in browser (what browser?) or some errors in Roundcube logs (time exec limit or sth)? Did you try with 0.8?

It take about 2 minutes to open imap mailbox with one letter like in example. IE or mozzila - show "Loading", and open mail after 1.5-2 minutes. Also php process take 100% cpu at this time on a web server.

I can confirm this bug in stable version 0.7.3

"Hangs" - means roundcube web interface doesn't load inbox messages list (messages list is blank). Roundcube 0.8.2 also buggy.

I can reproduce this bug in:

Firefox 16.0.2
Opera 12.02

I copied both mails into my inbox and have no problem with listing messages or displaying them. Enable imap_debug to check what (and how fast) is messages list returned from IMAP server to Roundcube. Also you could try to debug ajax request response in browser. Describe your server environment, what IMAP server, PHP, OS (versions)?

Problem solved, not a bug.

After we disable php idn module (extension=idn.so) all works great!
