Sorry, I should have said; I'm running 2.2.1

On Tuesday, April 23 at 10:52 AM, quoth Kyle Wheeler:
Hi,

I got all excited about IMAP NOTIFY support and tried enabling mailbox_list_index on my server. Unfortunately, I rather quickly ran into trouble of the segfault variety. This prevented me from doing basic things like seeing the contents of some of my folders. Disabling mailbox_list_index got me back up and running, but... darnit, that's annoying. The only message I got in my log file was this:

imap(user@domain): Fatal: master: service(imap): child 6899 killed with signal 
11 (core dumped)

If I can help track this down, please let me know. Here's the backtrace:
