Hi list, I've been investigating all morning a weird mailbox crash in roundcube.
Symptoms: a user contacts me because he/she can't open a folder in the webmail. The webmail hangs and finally crashes. On the server, I see a php5-cgi process using 99% of cpu. I use spawn-fcgi with nginx so killing the crazy process solves the issue, but it reappears if the user click on the folder again.
I had the problems twice already, and it's always caused by a weirdly formatted message. Today's message is here: http://pastebin.com/3kKRPvQR
It's difficult to track down, but I eventually figured out that the imap debug log would stop on the guilty message. Removing it, and reconstructing the mailbox (in cyrus-imap) fixes the issue.
I'm wondering if this issue is roundcube related, or a problem with php, the content encoding or maybe the weather (!). The system is running on Debian Squeeze with roundcube 0.5.2
Your advice are most welcome.
Cheers, Julien

I must add that the mailbox is still completely functional with thunderbird, which rules out the probability of a problem in cyrus-imapd (or, does it ?).

Works for me with Dovecot and svn-trunk version. I'd like to see the last part of imap_debug log just before the crash.

I've seen the log on priv. The problem is with "FLAGS (\Seen [SPAM])" part of the server response. Flag name must by an atom string in which "]" character cannot be used. In this case Roundcube makes infinite loop. I'll try to fix this.

That's great, thanks a lot. I can provide more data if you need to. And I'll be happy to test the patch whenever you have one.

Fixed in r4914. I'm just curious from where is the "[SPAM]" value? Maybe it can/should be fixed in other place too.

It works fine. I'll keep an eye on it for a few days. Thanks for the fix !

What do you mean exactly ? This [SPAM] header is added by DSPAM on the system.

Not the header, the IMAP flag. It's from Courier or Sieve, I think.
