The iOS Mail app is VERY sensitive. I can't tell you how many times  
I've crashed it (and the entire system on occasion as well) while  
developing this code.

This behavior is usually due to it receiving an email containing  
invalid UTF-8 data. Looking at the chuck of log you posted my bet  
would be a charset issue. We currently perform a number of checks to  
ensure we send valid UTF-8, and if we can't 100% guarantee this is the  
case, we remove all non 8 bit characters before streaming to the device.

The best way to figure out exactly what is going on is to figure out  
which email is causing iOS to choke. You can use the synclog to see  
exactly which emails were sent to the device in the last response and  
go from there. Remove each of those emails one by one until the folder  
starts syncing again. Once you've found the offending email, you can  
send it to me privately (if you feel comfortable doing so) and I will  
try and see if it's something that needs to be fixed on Horde's side.

Nope. It's expected, but only when enabling the synclog. Not all email  
bodies are shown (some make use of temporary streams for the body -  
mostly MIME mails - and we don't output the content of the streams to  
the log).
